cgjherr writes *"If the recent financial meltdown has left you wondering, 'When does exponential decay function stop?' then I have the book for you. Advanced Excel for Scientific Data Analysis is the kind of book that only comes along every twenty years. A tome so densely packed with scientific and mathematical formulas that it almost dares you to try and understand it all. A "For Dummies" book starts with a gentle introduction to the technology. This is more like a "for Mentats" book. It assumes that you know Excel very well. The first chapter alone will have you in awe as you see the author turn the lowly Excel into something that rivals Mathematica using VBA, brains, and a heaping helping of fortitude."* Read on for the rest of Jack's review.When I first opened this book my mouth just dropped. It had been years since I had seen a book typeset using LaTeX. But in an instant it made sense as the book is crammed packed with the kind of equations that would have been a nightmare to build with any other tools. Chapter after chapter has everything a really smart person needs to do curve fitting, statistical measures, differential equations, time-frequency analysis. But don't expect a play by play here. You will get the equations, set within a few dense paragraphs, with maybe a spreadsheet and a chart or two to show the results.

The first chapter concentrates on the getting the most out of Excel as a tool. All the chapters that follow dig into specific data analysis techniques. Chapters two, three and four are on least squares. Chapter five and six cover the analysis in the time domain including fourier transforms. Chapter seven covers differential equations. Chapter eight returns to Excel by digging in deeper into macros. Which leads into chapter nine, where we dig deeper into basic mathematical operations. Chapter ten covers matrix operations. And chapter eleven wraps it all up by giving you some spreadsheet best practices.

In University style there are also some exercises that you can do along the way if you want to tweak your brain pan a little more. To amuse myself I tried a few and I believe the book would have assessed my attempts 'wanting' if it had a voice to tell me.

Where most books like this would have several authors this book has just one; Roberte de Levie. This means that the tone, style and quality of the book is consistent throughout. A fact that you will come to appreciate as the book wades in ever increasingly deep data analysis concepts as the chapters roll on.

Though I would have preferred the book to have code samples in C#, I understand that the language of Excel is VBA and I guess I have to live with that. Thankfully VBA has come a long way and if you so inclined it would likely be easy to translate the code into C#, Java, or whatever else you like.

The fact that one person wrote the book left me wondering, "Who is this guy?" In my minds eye I kinda of figured he would look like one of those pulsing brain guys from Star Trek. Turns out he is a professor at Bowdoin College. And his fields of study include ionic equilibria, electrochemical kinetics, electrochemical oscillators, stochastic processes, and a whole lot more stuff that almost seems made up to sound impressive.

When this book isn't serving as an amazing reference for both Excel, scientific problem solving, or just insane equations it serves other purposes as well. It's a handy portable IQ test, as the count of pages you can grind through in one sitting, plus 90, is roughly your intelligence quotient. And if you fail at that you can always put a copy of the book, along with the Orange Bible, under your pillow and try to osmose your way to becoming the Kwisatz Haderach.

In all seriousness, this is a great book. It represents the kind of in-depth work and research we used to see in books that came out twenty years ago. Robert is to be applauded for his work. This is an excellent resource for anyone looking to do scientific data analysis but who was unaware of the powerful capabilities that Excel provides that is likely waiting just one Startup menu click away.

The book is not without fault. I would have preferred that it had been in color, or at least have one color section to show some of the more impressive visualizations that I'm sure would look great in color. In addition the index is silly short for a book that clocks in at 700 pages. But those are only minor quibbles for what is all-in-all an amazing piece of work.

## Why All Bailout Packages Will Fail (-1, Offtopic)

## Anonymous Coward | about 6 years ago | (#25221079)

I've been thinking about this for a while, but I think I understand why the majority of the American people are against the current bailout package, and why ultimately all bailouts (whether for banks, mortgage holders, or taxpayers in general) will fail.

The root of the problem is not economic but sociological in nature. No amount of economic carrots will fix the problem, despite the fact they may delay the crash or draw it out into a painstakingly long-term affair. Individidual productivity has dropped off as people have become depressed with their jobs, which seem to absorb ever increasing amounts of their time and effort.

Americans have become disillusioned with going after material at the expense of building relationships. People are addicted to their jobs and have delayed finding a partner of the opposite sex, getting married, and having children. Their job brings them immediate stability and shiny things; however, they know their long-term stability is at risk.

I think a majority of the population would appreciate a breather from the corporate world, and if there are large swaths of people in the same position, that gives them ample chance to meet with other people who have plenty of spare time in order to build relationships that cannot be built barhopping on Friday nights.

Maybe I'm projecting my thoughts too much on the rest of the populance, but I know very few people my age (~30 years old) who have even started building a family, and that's quite frankly, distressing. The economy isn't everything. The crash will happen. We will survive. Let it happen swiftly and let the recovery happen in the near term.

There is OBVIOUSLY a reasonably large market for something simpler then LaTeX and Mathematica in a lower price point, yet with more function and transparency (and accuracy?) than excel could ever offer.

Maybe an "output to excel" function to satisfy the plebes? I dunno. I just keep seeing this fight on /. and wondering why each time.

There's a book called Tex Unbound that gives lots of other ways to make charts in TeX/LaTeX that are way better than Excel output (or most other graphing packages IMO).

What in the world are you talking about? :)

LaTeX is a markup language. You can express math with it, but it doesn't do anything for you in terms of analysis.

Excel is good for small data sets and quick looks at stuff - but painful to develop in.

Mathematica requires college-level calculus and linear algebra... not PhD stuff by any stretch.

Anyway, you left out Matlab - which is pretty awesome. Depending on what you are doing, there is also R, Maple, Minitab, MathCAD, yada, yada, yada. Lately I've been doing stuff in Python... SAGE is pretty nifty, and the NumPy/SciPy stuff is coming along well (it is included in SAGE).

Python for scientific analysis [scipy.org] ,

Python is the solution I recommend for everyone who looks for tips on advanced Excel uses. Excel is OK if you just want some quick and dirty solution for a small problem, but if you have to go to the trouble of reading a book, Excel is clearly not the best solution.

For scientists and engineers who need something more than what Excel (and possibly Matlab) offers, I recommend starting with either A Byte of Python [swaroopch.com] or Dive Into Python [diveintopython.org] .

You were modded funny, but many of the quants at the BoA create their mathematical models in Excel VBA (these are quants with Ph.Ds in physics). These get handed over to the software dev team to be recoded in some other language like Java or C#.

Some other places have had some success persuading their quants to use better tools like MATLAB, but Excel is still one of the primary tools used for modeling owing to its universal availability and folks' familiarity with it.

It boggles the mind, I know.

Why isn't it a good idea, and does this apply equally to OpenOffice?It's OK for simple stuff, but trying to do something like implementing a loop in a spreadsheet. And yes, the criticism applies to OO as well.

There are very good packages out there - some open source - for doing scientific analysis. I'd recommend R or Octave (a matlab clone), personally. Also, Python + NumPy + SciPy + Pylab is great for doing Matlab-like things, and it's all free as well.

## Loops in spreadsheets (1)

## weston (16146) | about 6 years ago | (#25221815)

It's OK for simple stuff, but trying to do something like implementing a loop in a spreadsheet.This is one reason the VB scripting turns out to be highly useful. But that said... for half the things loops might be useful for in a normal context, they're wrong in a spreadsheet. Iterating over a set of data isn't done with loops, it's done with applying formulas over a range of cells. And if you turn on iteration for the spreadsheet, it *is* possible to build flow-controlling state machines without using the scripting engine. Not particularly natural for most imperative programmers, but definitely possible.

So I don't think loops are the issue. My understanding is that the biggest problem with using Excel for detailed number crunching is in how they handle some precision/float issues.

## Re:Loops in spreadsheets (2, Interesting)

## MightyYar (622222) | about 6 years ago | (#25222175)

This is one reason the VB scripting turns out to be highly useful.

I recently had to do a project in VBA/Excel after years away from it, and it made me want to dig my eyes out with a spoon.

Don't ever write custom functions... ever. You'll thank me when you don't have to worry about whether or not they silently fail.

And once I had my whole spreadsheet corrupt for some reason... had to open on a Mac and re-save it. Then it worked fine on the PC again! Aye.

- Crappy visualization

- Sometimes a 2-D data structure ain't the best

- Excel's pivot tables get the job done, but they have some pretty inconvenient behavior

- Sometimes you want to define a formula once and apply it everywhere, not once per row (when you have ~60k rows). Excel can really bog down when you start having a lot of formulas for big datasets; other tools handle this better

- Last I checked it still had some accuracy issues

- And many more

A lot of the time Excel is fine. But it's usually not the

besttool for the job.BTW last I checked, OO had a workable link with R. I think it was a Summer of Code project; I don't know the current status.

I certainly run the test suite before using a new build of SciPy/NumPy - but I'm largely dependent on the developers.

Still, in Excel I've caught errors and so now I usually calculate things in two different ways to try and catch stuff. For instance, fit a line using both the built-in methods and the solver. Don't use the line fit in the graphing tool - that's one error that I found.

Well, 2007 has bugs in it. I don't use Excel, I use something that can utilize math correctly. Have you checked your spreadsheet program? Or do you just assume that Microsoft does everything correctly?

I use Excel for daily business functions and data analysis, and will continue to do so, but I don't assume Excel is perfect. I do what I should do with any program I use for calculations, though: I stay aware of all of the quirks and bugs I can of the program, and try to work around them.

Every program is going to have a bug or two (or five thousand, seeing as Excel is part of MS Office), but part of working with software is to know what those are and learn to not let them ruin work.

Care to expand on why you think you can't do 'meaningful scientific data analysis in Excel?'

A while back, and this might not be true today, Excel gave errors when doing certain functions. [maryparker.org] In this case it was standard deviation.

Several scientific papers came out which had to be recalculated using mathematica or matlab or spice or something, because the data couldn't be trusted after the error was exposed. A small error introduced can be very large, depending how it was used and in the order the data were gathered ... thus Excel got a very bad name for doing "meaningful scientific data analysis."

Someone else has already posted a link to a page that nicely summarizes many (not all) of the problems with using excel for science. But there is virtually no statistical technique which isn't already better implemented in R (free) and many other statistical packages. Real stats packages provide implementations of a given technique that are at least as reliable, provide more control, more options, more diagnostics, and often more guidance. The built-in stuff in Excel is so oversimplified that I think if you're really forced to use it for serious statistics, you'd have to re-implement things using basic arithmetic operations. It's graphing capabilities, last time I checked, lacked the majority of even the most basic kinds of statistical/scientific graphs/plots. Sure, you can do this or that in Excel, and if you're willing to put in enough work you can often get what you really need out of it. But it's rarely if ever the best tool for the job of scientific data analysis.

I don't review books about reading them, and this is no exception. But I do have an informed opinion about the premise of this book (and to a lesser extent about the level of insight of a reviewer who seems, to put it mildly, easily awed). The premise that Excel is good to use for scientific data analysis is pretty deeply misguided. I'd be happy to be convinced otherwise if I were really wrong, but I can only set aside so much time for listening to arguments from nutcases (just in case one of them may have a point). I'm sure if I actually read this book, I'd learn about various useful things Excel can do that would surprise and impress me. But I already have all the information I need to form a reliable opinion on this question, and I value my time too much to read books about space aliens living among us or about doing analysis in Excel.

Truth to tell, I use openoffice calc (more or less an Excel clone) quite a bit for research-related things. But I'm careful with it, and don't rely on it for much more than moving numbers around.

If you're willing to spend hours setting it up, and getting it to "sort of" work with touch-ups required every few days. Maybe I'm a dolt, but I never got any of the embedded-R interfaces to work satisfactorily. The documentation was always just too out-dated, and there were too many surprises and inconsistencies. By the time I worked them out, it would have been easier to do it another way.

If you're in a unix environment, I suggest looking at littleR [vanderbilt.edu] which makes the R libraries usable in unix "piping" style. Useful for batch processing, but of course not good for real-time.

In windows, you're going to have a hard time with either of these. That RExcel mentioned above looks interesting, even though it offends my sensibilities. ;-)

Perhaps because you work in an environment where they have a corporate culture of expecting results in an Excel spreadsheet?

Surely we can admire someone for mastering a tool to the point where they can do extremely complex operations using that tool then writing a book on how to learn to do the same thing? If you can learn to do this in Excel and if Mathematica is a superior product then surely learning how to do this in Excel will only make it easier in Mathematica?

I admire the folks that do incredible paintings in MS Paint, even if I have no desire to learn how to do so (for instance this: http://diamonster.deviantart.com/art/powerdraw-17908194 ) I don't see how this differs really.

On the other hand, it's disgusting to have so much productivity and economy wasted on shoe-horning the godawful Excel into pretending intelligence. Not to mention how error-prone it is; a mistake in MSPaint is mildly annoying; a rounding error or outright bogus value in science is close to lying.

But then, remember that beautiful maths are just a feature of LaTeX, not the main focus. It's a document processor, which is nice in that someone like me with little aesthetic taste can simply specify the *content* of my paper and let LaTeX worry about the layout. And maybe you can write a paper in word that looks as good, but I know I've never been able to.

It may be close now in output quality, but any search, point and click system will always be inferior to LaTeX when it comes to equations.

## Spreadsheets are the right tool ... (4, Funny)

## MacTO (1161105) | about 6 years ago | (#25221407)

You see, there is a fundamental problem in science and the problem can be summarized as this: how do you get the right results in order to optimize the grants that you receive. Spreadsheets are ideal for this purpose for two reasons. First of all, they are designed to handle financial data. This is great because financial data are what grants are all about. For example: will result X allow for a conference in Hawaii or California this year.

The other big reason to use spreadsheets is that they make data more maluable. Normal scientific tools make it difficult to micromanage the data that you acquire, partially because the people who produce that software have this mistaken notion that data has to be managed in a consistent way. So you're usually stuck doing the same thing to an entire dataset, and it's even difficult to treat different datasets in different way. But spreadsheets expose all of that data, so it is easy to tweak an observation here and a variable there to get the desired result to maximize your grant.

So you see, spreadsheets are a tremendously valueable tool for scientists. It is the best tool for the job.

Spreadsheets are right for much of what you state... but surely one could use another tool to generate the data and simply import the data into Excel to perform more basic operations.

For some things, especially complex math, spreadsheets simply are much less efficient and completely unnecessary.

Hardcore data analysis in Excel is almost always a bad idea. You can almost always find a way to do it in excel, and you can almost always find a way to do it better, faster, and cheaper somewhere else.

R, MatLab, Mathemateica, Python/Numpy, SigmaPlot, and any number of old, well written, debugged and vetted numerical libraries written in C or Fortran. I've used all of these at various times to solve something that a co-worker couldn't figure out how to do in Excel.

I fit quick linear regressions in Excel. For *anything* else, there is a better choice.

Hardcore data analysis in Excel is almost always a bad idea. You can almost always find a way to do it in excel, and you can almost always find a way to do it better, faster, and cheaper somewhere else.I would have to disagree, having used both Excel and "rolled my own" in pure C.

My own code runs a few

thousandtimes faster, I know exactly where the errors might pop up, and I don't need to try to squeeze the data into a form suitable to whatever MS decided I should use this week, I just handle anything I want, however I want it done. I can graph it any way I like, save the data to any format I like ("Hmm, I wonder what that functionsoundslike... Okay, where'd I put that RIFF header code?"), and I can implement ways to massage data never seen outside pretty hardcore mathematical research journals.All of that, while undeniably "superior" in nearly every aspect to Excel, takes

timeto implement - Potentially quite a lot of it.And then we have Excel... I can take list of raw numbers in most common list- or table-like formats, paste it in, and run a polynomial regression on it in 30 seconds flat, with another minute or two to graph it in 99% of the ways I would ever think of using. I can prettify the data for showing PHBs with a half-dozen clicks. I can save my results in a format anyone can view, without having to write a specific set of routines to export this particular blob of data to format-X. I can trivially preprocess the data in a wide variety of ways to see how it affects the results, and see the changes happen as I go.

In short, Excel makes it much,

mucheasier to "play" with data than most programs designed specifically for "serious" mathematical work - In much the same way that I can do most simple image touch-ups in MS Paint faster than GIMP would even finish loading all its plugins.Now, I sure as hell wouldn't publish (or more likely for me, sell to a client) results or methods based on a quick-n'-dirty Excel sheet... But I can try a hundred different approaches to working with the data in the time it would take to rigorously code just one of them, and then spend my actual effort (aka "the client's money") on coding up what looks like the

## slashdotlurker (1113853) | about 6 years ago | (#25221571)

I know it is popular and many science and engineering faculty lazily encourage their graduate students to use it. However, something like matlab beats the crap out of excel any day. Spreadsheets tend to obfuscate relationships between data, require a lot more clicking (read human intervention) and waste time that could be spent thinking about the data, and are singularly unsuited for analysis of similar sets of data (a situation any scientist faces when he has to do a series of experiments).

Matlab might take sometime to initially write the scripts, but it is so powerful and extensible that no one in their right mind would want to use excel. If you are a slave to spreadsheets, get yourself a copy of Microcal Origin or Labplot.

Excel is especially unsuited to the task of preparing figures for scientific publications. The default formatting is at once wrong for the task and hard to change. Once you set your preferences in matlab (easy to do), you are set for life.

In my experience, excel is also rarely used for anything serious outside of US. Maybe its an indictment of how lazy, slow witted and easily misled our pool of talent is becoming.

SPSS has now become the standard data analysis package for quantitative studies in social sciences. It's very crappy software, and it wouldn't take a whole lot of augmentation to get Excel do what SPSS does.

The problem is that social scientists don't want to mess with the internals too much, and SPSS made for them a point and click interface - in effect, they out-Microsofted Microsoft. They charge an insulting $1500/copy and completely dominate the universities, so they're making good money.

They seriously need some competition.

Serious researchers do not use excel. Period. Ask scientists in any national laboratory. Excel is a toy designed for simple accounting talks. It is slow, it is limited but, most importantly, it makes error prone since it refers to variables by their position on the spreadsheet, not their name or meaning or role in the workflow of the computation. I guess it is an ok tool to teach undergrads who will never go into sciences.

It does not mean that there is actually a book written in 1988 on that subject. Merely, a book of similar quality, not even necessarily on the same subject.

Its clear that the reviewer is not qualified to review this text. First, if they were familiar with scientific data analysis, they would not use Mathematica for their ridiculous comparison. Mathematica is also the wrong tool for the job. At least it does math correctly, something Excel cannot claim. [doi.org]

You haven't seen a book typeset in LaTeX recently? What scientific computing books do you read that allow you to avoid LaTeX for years?

Excel is not the right tool for the job. If you are going to put in the time to learn some new math, learning a better tool along the way makes sense.

Get a different book, and a different software package.
