AMS 315, Fall 2010 Computing Handout 1 Statistical Programming Languages A number of computer programs specialize in performing statistical computations: SAS, R, SPSS, and Minitab among others. Since the SAS program is currently the most widely used in pharmaceutical companies and financial institutions, I recommend that you learn it; and I will focus on it in this class. SPSS is widely used among social scientists and market researchers. It is most commonly used in interactive analysis (researcher requests analysis, and program computes results immediately). My experience is that its interactive pull-down menu is vastly superior to that of SAS. The R statistical program is free, and many statistical researchers make the R-code that computes new methods available on the web for free. Minitab is widely used in teaching of statistics but is not used as often in business. Finally, the Excel spreadsheet program can perform a number of statistical calculations and should become an ever stronger competitor to SAS. Using SAS There are two modes for using SAS. The first is an interactive mode in which you use a pull-down menu. The second is to create a SAS program. Learning how to write SAS programs is a valuable skill. In reporting the results of a research project in a scientific paper, I prefer the use of the SAS program with an organizational rule of one program for each table or graph. This is very offensive to my programming colleagues. Some of them develop a gigantic program in
