Graham is correct about R. As I am now officially retired, I have decided not to try to master R…at least for now.
Graham neglected to mention a powerful and intuitively easy-to-use program: SPSS, like SAS, etc. is expensive but pretty easy to use. Several years ago, I had occasion to use it on an out-of-the ordinary problem. Although I hadn’t used it for 15 years, its GUI allowed me to set up 90% of the problem and doing a script for the remaining 10% was quite easy. I haven’t used Stata or Genstat, but I can offer an opinion on SAS:
SAS is a powerful program, but unless it has dramatically changed, its GUI is decades old and it is a PitA (Pain in the A**) to use. Very non-intuitive. And, as someone else has said, the phrase “SAS Help” (referring to its Help file) is an oxymoron. Years after other stat software could easily import Excel files, it offered a 3-day class in how to import Excel data into SAS. Unlike SPSS, one must go into contortions to do anything out of the ordinary in SAS.
