Abstract: 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 update this paper several times a year at http://r4stats.com to provide an ongoing view of the software. Recent updates include adding a brief discussion of Quora.com (9/13/2011), Stack Exchange and Stack Overflow.com (7/12/11), updating the blog counts in Table 3 (6/21/11), and replacing Fig. 6 with the latest one (5/26/11).
Estes resultados confirmam as evidências prévias: o R continua dominando as paradas de sucesso.
