Hi all,    I have a dataset that is seperated into 4 groups (disease1, disease2, disease3, disease4). For each individual, I have several variables to test (biochemical variables such as creatinine, urea...).    I coded a npar1way procedure to perform a Kruskal Wallis test to determine if there was a statistical difference for a given variable between the 4 groups: proc npar1way data=data_descriptive_workingfile wilcoxon; var creatinine ; class group; run;   This worked well.   I know want to compare the data within the classes : perform a Mann Whitney U Test that compares creatinine between Disease1 and Disease2, Disease 1 and Disease3, etc. I do not want to perform a Steel-Dwass-Critchlow-Fligner test because I would like to use another type of post-hoc analysis Is there any way to code that ?    I am running on Sas OnDemand for Academics   Many thanks in advance for your help,  Maxime ...
