The new STRATA statement provides stratified rank-based analysis of two-sample data. The following score types are available: Wilcoxon, median, normal (Van der Waerden), Savage, and raw data scores. Rank-based scores can be computed by using within-stratum ranks or overall ranks; strata can be equally weighted or weighted by stratum size. The new ALIGN=STRATA option in the PROC NPAR1WAY statement aligns responses by location measure within strata before performing unstratified analyses; location measures include the stratum median, mean, and Hodges-Lehmann shift.
