Usage Note 22620: Can I get nonparametric multiple comparisons from PROC NPAR1WAY?
No, PROC NPAR1WAY does not provide multiple comparison methods. Some people rank-transform their data and use the normal-theory
methods in PROC GLM (Iman 1982, "Some Aspects of the Rank Transform in Analysis of Variance Problems," Proceedings of the Seventh Annual SAS Users Group International Conference, 7, 676–680). It might also be reasonable to rank-transform the data and use the permutation resampling method in the MULTTEST procedure.
The PharmaSUG paper "Simultaneous Nonparametric Inference in a One-Way Layout Using the SAS System" provides a description of Dunn's procedure for adjusted comparisons. Macro code for this technique is available from the author of this paper.

For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
