In addition PROC NPAR1WAY produces the following tests for scale differences. PROC UNIVARIATE can also be used to produce nonparametric confidence intervals around the median.

Output 8731 displays the results of the Wilcoxon two-sample test.

Wilcoxon signed rank test a rank test used in nonparametric statistics can be considered as a backup for t-test where the independent variable is binary but the dependent variable is not normally distributed. PROC NPAR1WAY displays a standard analysis of variance on the raw data. When trying do a wilcoxon rank sum test on a small comma-delimited input text file 96 obs in PROC NPAR1WAY the program keeps running like stuck in an endless loop and never completes. The statistic is 526656 with 4.
