Dear List,

First off, this is completely off topic, but I thought others might find it interesting. The good people at IBM are apparently providing written interpretations of results now. I was working with a student the other day with simple nonparametric tests using SPSS, and under the nonparametric test tab, it defaulted to something like "Let SPSS decide which test to use". Even when a test was manually selected, the output was (of course formatted in one of SPSSs (in)famous tables):

Null Hypothesis: The distribution of DVtest (the variable) is the same across categories of group.
Test: Independent-Samples Mann-Whitney U Test Sig: .246
Decision: Retain the null hypothesis.

In a similar vein, here is a quote from Wikipedia (http://en.wikipedia.org/wiki/Q_research_software) about Q:

"Q uses expert systems that automatically select appropriate significance tests based on the structure of the data"

Has anyone seen similar trends elsewhere? It gave me renewed appreciation for the thoughtful consideration of the R developers in even making some tests convenient to access (e.g., http://r.789695.n4.nabble.com/Standardized-Pearson-residuals-td3355110.html ).
