Hi all,
I am running a multi-level modeling using complex survey data, which used a stratified, clustered, and unequally sampling design. For my research questions, I have to select a subsample, but due to the weight issues, I think I am not able to create a new tiny dataset which only includes my subsample. For regular regression analyses, I use SVY, subpop (): regress command, but I wonder if it would be possible to use a similar command for MLM with a subpop and continuous outcomes in Stata. If not possible, any thoughts on another approach to deal with it?

Thank you so much!
