The Popularity of Data Analysis Software
This page presents various ways of measuring the popularity or market share of BMDP, JMP, Minitab, R, R-PLUS, Revolution R, S-PLUS, SAS, SPSS, Stata, Statistica, and Systat, as well as two implementations of the SAS Lanugage, Carolina and WPS. I plan to update this paper twice a year at http://r4stats.com to provide an ongoing view of the software. The most recent update was on March 20, 2011 when I added updated most the data overall and added coverage of Statistica, WPS and Carolina.
