Stata in Google Scholar
In the academic world the use of analytical/statistical tools is essential to do research. The data analysis and empirical research has grown exponentially in academic publications as PCs became universally affordable, -- there is an interesting graph showing the growth of empirical research in the economic literature (vs theoretical) that unfortunately I couldn’t find.
The most widely used of those statistical tools is R, as the graph below shows. However, Stata is surprisingly matching R. Strangely enough Stata is not that ubiquitous outside the academic world.
