I am using sample weighted data. I want to compare a result before and after an intervention. I would like to use a Wilcoxon signed-rank test. I know I cannot use the signrank command with weights. I have seen the Somers' d ado file. Can I run the Wilcoxon test or some other nonparametric test with that package using weighted data, and if so, would appreciate help on the commands. Thank you.
