I was able to produce a stratified Wilcoxon test, but I can't figure out if it is also possible to obtain stratified Hodges-Lehmann estimates for the location shift.
If that option is not available, I am not sure if it would make sense to compute it as a weighted sum of the location shift for each strata? I could not find any reference on that.
Program code:
proc npar1way data=input hl wilcoxon;
CLASS treatment;
VAR variable;
EXACT hl;
STRATA strat1 strat2 / wilcoxon;
run;
Thanks!

Check this reference out (ASA members can get around the paywall):

The authors cover the HL aligned rank test, with some adaptive testing schemes, and are quite pleased with the results.
