PASS is the Power Analysis and Sample Size program. It analyzes t-tests (one mean; two means), F-tests of several means, chi-square tests (goodness of fit; contingency table), tests of proportions (one; two), log-rank survival tests, correlations (single; two correlations), ANOVA (fixed effects; randomized block; repeated measures), log-rank tests, regression (multiple; logistic), and bioequiva- lence procedures. It then produces AScii and graphics files reporting power levels. It can also be used for determination of needed sample size to achieve a given power level with a given procedure. Rank- and-file social scientists who merely want to estimate sample size during the design process will find PASS too sophisticated and non- user-friendly for their needs. Methodologists who understand power analysis, however, will find PAss an extremely useful and effective tool.
