Dear Aca,
why don't perform bootstrap ANOVA test in oeder to allo for the skewed
distribution of the response variable?
Kind Regards,
Carlo

Oggetto: st: Kruskal-Wallis equivalent for survey data with pweight
I have a simple question about testing length of stay (LOS)
differences among 5 groups. The response variable (LOS) has a skewed
distribution. I have previously transformed the LOS (log
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
