Qual é o software de análise de dados com maior popularidade? Robert A. Muenchen nos apresenta a resposta num interessante artigo. A metodologia consistiu na análise das vendas, popularidade na internet, números de downloads, entre outros fatores para determinar qual software é o mais popular. Segue o resumo:
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/popularity 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.
Após a análise de diversos fatores o autor concluiu que o R é o software mais popular. Segue a conclusão:
By most of the measures discussed here, R is competing well with the commercial software vendors. However, I advise not over generalizing from this data. SAS and SPSS continue to dominate the corporate world and Stata is doing quite well in the scholarly arena. Each of these packages is dominant in one market or another. I'm interested in other ways to measure software popularity
