We can study the relationship of one’s occupation choice with education level and father’s occupation. People’s occupational choices might be influenced by their parents’ occupations and their own education level. Examples of multinomial logistic regression.
Stata Vs Spss Software That Allows
This multi-level regression is used for interval measured outcomes.The single equal, , is used as a set equal operator. On the other hand, Stata allows multi-level regression. SPSS is the best statistics software that allows you to perform Simple Statistical comparison tests and the appropriate test. I’m posting the table here in hopes of useful comments. I think most people choose one based on what people around them use or what they learn in school, so I’ve found it hard to find comparative information. Lukas and I were trying to write a succinct comparison of the most popular packages that are typically used for data analysis.
Two big divisions on the table: The more programming-oriented solutions are R, Matlab, and Python.

In terms of functionality and approach, SciPy is closest to Matlab, but it feels much less mature. You can use SAGE or Enthought but neither is standard (yet). Scipy.linalg)? And then there’s package compatibility version hell. Why does matplotlib come with “pylab” which is supposed to be a unified namespace for everything? Isn’t scipy supposed to do that? Why is there duplication between numpy and scipy (e.g. Python “immature”: matplotlib, numpy, and scipy are all separate libraries that don’t always get along.
R’s is surprisingly good (Scheme-derived, smart use of named args, etc.) if you can get past the bizarre language constructs and weird functions in the standard library. Python is clearly better on most counts. It sometimes doesn’t seem to be much more than a scripting language wrapping the matrix libraries.
I’m wondering, how good is it compared to R? I’ve never used the Matlab Statistical Toolbox. Very popular in machine learning. Matlab is the best for developing new mathematical algorithms.
SPSS and Stata for “Science”: we’ve seen biologists and social scientists use lots of Stata and SPSS. I personally haven’t used either… Stata is a lot cheaper than SPSS, people usually seem to like it, and it seems popular for introductory courses. SPSS and Stata in the same category: they seem to have a similar role so we threw them together.
There were boatloads of SAS representatives at that conference and they sure didn’t seem to be on the leading edge. Then he asked if SAS was even offered as an option. At that R meetup last week, Jim Porzak asked the audience if there were any recent grad students who had learned R in school. I know dozens of people under 30 doing statistical stuff and only one knows SAS. Another important thing about SAS, from my perspective at least, is that it’s used mostly by an older crowd. (ANOVA, multiple regressions, t- and chi-squared significance tests, etc.) Certain types of scientists, like physicists, computer scientists, and statisticians, often do weirder stuff that doesn’t fit into these traditional methods.
(This was an interesting point at the R meetup. (Hive? Pig? Or quite possibly something else.) Hadoop, MPI) but It’s an open question what the standard distributed data analysis framework will be. There are a few multi-machine data processing frameworks that are somewhat standard (e.g. If your dataset can’t fit on a single hard drive and you need a cluster, none of the above will work.
SAS people complain about poor graphing capabilities. It’s just a whole different ballgame with that large a dataset.) But Itamar Rosenn and Bo Cowgill (Facebook and Google respectively) were talking about multi-machine datasets that require cluster computation that R doesn’t come close to touching, at least right now.
Excel has a far, far larger user base than any of these other options. Matplotlib follows the Matlab model, which is fine, but is uglier than either IMO. Matlab’s interactive plots are super nice though. One view I’ve heard is, R’s visualizations are great for exploratory analysis, but you want something else for very high-quality graphs.
Most of the packages listed above run Fortran numeric libraries for the heavy lifting. They are super fast and memory efficient, but tricky and error-prone to code, have to spend lots of time mucking around with I/O, and have zero visualization and data management support. Another option: Fortran and C/C++. But it does massively break down at >10k or certainly >100k rows.
We used SAS in litigation consulting because we frequently had datasets in the 1-20 GB range (i.e. I’d love more information on this for all these options.Aug 2012 update: Serbo-Croatian translation.>I know dozens of people under 30 doing statistical stuff and only one knows SAS.I’m assuming the “one” is me, so I’ll just say a few points:I’m taking John Chambers’s R class at Stanford this quarter, so I’m slowly and steadily becoming an R convert.That said, I don’t think anything besides SAS can do well with datasets that don’t fit in memory. I think knowing where the typical users come from is very informative for what you can expect to see in the software’s capabilities and user community. ( Here the article that inspired this rant.)
I’ll be very interested if this R + Hadoop system ever becomes mature: In my work at Facebook, Python + RPy2 is a good solution for large datasets that don’t need to be loaded into memory all at once (for example, analyzing one facebook network at a time). I don’t have quantitative stats on SAS’s capabilities, but I would certainly not think twice about importing a 20 GB file into SAS and working with it in the same way as I would a 20 MB file.That said, if you have really huge internet-scale data that won’t fit on one hard drive, then SAS won’t be too useful either. I recall a Cournot Equilibrium-finding simulation that we wrote using the SAS macro language, which would be quite difficult in R, I think. In this relatively narrow context, it makes a lot of sense to use SAS: it’s very efficient and easy to get summary statistics, look at a few observations here and there, and do lots of different kinds of analyses.
R obviously has a stronger statistics user base and more complete libraries in that area – along with better “out-of-the-box” visualizations. I would add that you are missing a lot of disadvantages for Excel – it has incomplete statistics support and an outdated “language” :)Python actually really shines above the others for handling large datasets using memmap files or a distributed computing approach. I don’t do much graphics, but perhaps check out “R Graphics” by Murrell or Deepayan Sarkar’s book on Lattice Graphics.This is obviously oversimplified – but that is the point of a succinct comparison.
The only other reason I can see to use them is if you have no choice, for example if you inherited a ton of legacy code within your Driscoll – good point! I was afraid to make performance claims since I’ve heard that Matlab is getting faster, they have a JIT or a nice compiler or something now, and I haven’t used it too much recently. I think you are basically operating at a disadvantage if you are using the other packages at this point. If there is something scipy is weak at that I need, I’ll also use R in a pinch or move down to C.
