Hello our esteemed advisors, I want to compare two data sets that have same variables but different IDs. I want to get a test of significance whether the variables have equal variances in both data sets. The test i desire to use include ttest or Mann Whitneys test. I have both continuous and categorical variables. have tried Proc compare but since IDS are different, the procedure doesnt seem to work. PROC COMPARE BASE=data1 COMPARE=data2 ALLSTATS MAXPRINT = (3,6); id IDnum; VAR x y z; RUN; I will be glad to get some advise.
