Hi all ,
I have a population of 3 variables rate1, rate2, group. The variable group has 3 levels (group1, group2, group3) and the distributions of the rates are not normal. How in SAS, can I determine which group has higher means vs another group? I would like for example to build a non parametric confidence intervals between different groups for each rate: CI (group1 - group2), CI (group1 - group3) and CI(group2 - group3). Thanks for the help.
