Based on an analysis of Google Scholar data on usage of statistical software, Bob Muenchen makes a forecast: R will overtake SAS and SPSS in 2015. Forecasting is extrapolation — always a tricky business — so Bob also provides these qualitative reasons why R will continue to grow at the expense of SAS and SPSS:
- The continued rapid growth in add-on packages (Figure 10)
- The attraction of R’s powerful language
- The near monopoly R has on the latest analytic methods
- Its free price
- The freedom to teach with real-world examples from outside organizations, which is forbidden to academics by SAS and SPSS licenses (it benefits those organizations, so the vendors say they should have their own software license).
See how Bob comes up with this forecast (using R, of course!) at the link below.
