Proc Npar1way Wilcoxon Paired. The normal approximation for the Wilcoxon two-sample test yields a one-sided p -value of 00421 and a two-sided p -value of 00843. The wilcoxon option will enable the Mann-Whitney U test.
The following statements are available in the NPAR1WAY procedure. The first is Proc ttest and the second is Proc means. PROC SGPLOT is used to provide boxplots for the number of bugs by treatment.
Wilcoxon Median Anova.
Well review both here. The NPAR1WAY Procedure Wilcoxon Scores Rank Sums for Variable score Classified by Variable group. If time use PROC GLM to generate least squares means and differences with confidence limits and to make pair-wise comparisons adjusted for multiple comparisons. Since this value is greater than 600 the expected value under the null hypothesis PROC NPAR1WAY displays the right-sided p -values.
