1. How to use FREQ procedure in SAS to compare proportions by non-parametric tests
(i) Fisher’s exact test (for two independent groups to test whether the association between two categorical variables exists.)
(ii) Rank-sum test by using NPAR1WAY procedures (to compare means of continuous outcomes for two independent samples)
(iii) Sign-rank test by using UNIVARIATE procedures (to compare means of continuous outcomes for two dependent samples)
