Statistical software packages for physical therapists. STATPAK for the IBM PC

If you have modestly sized files, modest computing requirements, and only a modest budget, look into STATPAK. Despite the limitations of STATPAK's computational accuracy, data-entry capabilities, and file-size restrictions. It is a package that provides many of the more frequently required statistical routines in physical therapy research. Besides, who knows when you'll need Fourier-transformed nonlinear correlations! Be prepared to spend an evening or two getting used to the cryptic program descriptions. Perhaps a future version will contain a tutorial with sample data to help the beginner get started; a general linear-model routine to permit ANOVAs on unbalanced Ns, assess multivariate hypotheses, and test the compound-symmetry assumption of repeated measured ANOVA would also be welcome. I would first recommend, however, that the documentation problems be addressed; at least let us find "Graphics" or "Chart" in the index, without having to guess that we should look under "Plot"!
