I have a simple question about testing the LOS differences among 5
groups. The response variable (LOS) has a skewed distribution.
I have previously transformed the LOS (square root transformation) and
tried parametric statistic (ANOVA using svy:regress), but not happy
when performing back-transformation for SD/SE. I rarely used
non-parametric statistics before even for non-survey data, so really
this issue is a hassle for me. I believe, however, that Stata has a
test equivalent to Kruskal-Wallis for survey data.
Any suggestions?

Thank you,
Aca
