Hi Statalisters,
I am running a regression analysis to compare two groups on my outcome y (while adjusting for some covariates) while taking into account clustering using xtmixed in Stata 11.
I would also like to calculate the Cohen's d value associated with this analysis. Normally I would calculate it as:
d = abs(mean_group1-mean_group2)/pooled sd
how can I obtain the pooled standard error? should I account for the clustering to estimate it?
Any help would be appreciated.
Thanks,
Fran
