add link to my review?

Would anyone be willing to add a couple of sentences to my review of free statistical software? http://gsociology.icaap.org/methods/soft.html This could be added into the main article section on reviews, perhaps saying something like what I wrote on my webpage "Basically, for correlation and simple regression, all gave the same results. Some also had the same results for forward stepwise." I only ask because I've searched the web and can't find any other review showing that the packages get the same results and so should be statistically equivalent. This seems like it would be useful information to have. Thanks Gene Shackman 03:45, 14 March 2009 (UTC)

call for comments

Hi Gene, I saw your note on the forum so just popped into check it out. Its an interesting article and certainly good information. I do not know anything about statistical software so cannot really comment on the topic at hand. Should there may be be a little more of a historical perspective? At present it reads like a "current" review that might become dated quite rapidly.

With regard to the following paragraph:

"Before using any statistical packages, it is generally a good idea to have a solid background in Statistics. Then the packages can be used to the best advantage, for example, to choose the most appropriate test, to make sure all the necessary assumptions are met, so that the appropriate conclusions can be drawn."

While this makes sense it is too general to be useful for a reader. Shouldn't there be specific examples of why some packages are better than others for any particular test? My first question would be "what makes these programs different?". Also, "why are some better than others for a particular test?"

Thanks for the comments. About "historical" - well, while some of the links may get to be outdated here and there, I think much of what is currently in the article is fairly stable. The packages mentioned are ones that have been around for a number of years. The reviews, articles and websites with listings and reviews are also in sources that are fairly stable, for example, journals, newsletters. Most of the tutorials, email lists and faq pages have also been around for a number of years. Should I add something about that, that most of these things have been around for some time?

about specific examples, and why some package may be better than others in some procedure... That certainly would be useful and I'm getting to that part, haven't written it yet.

and this leads to one question that I proposed above. As far as I know, there is only one source comparing the outcomes of the different programs, to show whether they are similarly accurate and what their output looks like, and the source is, well, mine. I wrote several reviews, here, http://gsociology.icaap.org/methods/soft.html. But this is at a site I own, so am I allowed to refer to it? There is the one other paper about the accuracy of easyreg and I do mention that, but mine is the only comparison that I could find, and I've searched. Could I refer to it, or would someone else be kind enough to add something about it to this article?

Thanks for the feedback and I'm certainly open to any other suggestions. Gene Shackman 15:12, 22 March 2009 (UTC)

With regard to historical, I was not thinking about the stability of the links or content but more about the history of these programs. Why were they developed? Who developed them? That sort of thing. Chris Day 15:45, 22 March 2009 (UTC)

I'll look into that, see if I can add something. Gene Shackman 17:14, 22 March 2009 (UTC)

what the devil is an NGO?

This is used all through the article -- Larry doesn't like abbreviations, especially ones that we (read "I") don't understand. Please change it, explain it, or remove it. Thanks! Hayford Peirce 15:28, 22 March 2009 (UTC)

I added the full name in the first paragraph - non governmental organization, like UNESCO. Gene Shackman 17:18, 22 March 2009 (UTC)

Thanks! I've never hoid it used before, but I suppose it's common enough. (Just did a little checking, it really does need a hyphen....) Hayford Peirce 17:32, 22 March 2009 (UTC)

Sociology

Just out of interest, why is this in the Sociology Workgroup? Chris Day 15:42, 22 March 2009 (UTC)

I suppose it's in sociology because I'm a sociologist, and sociology uses a lot of stat analysis. But I'm certainly happy to see other work groups added, psychology, some science ones, anything anyone is interested in. I just can't remember how at the moment. Gene Shackman 17:18, 22 March 2009 (UTC)
