However, even after changing the subpop() specification as suggested, it still gives me an error whereas the code runs perfectly if I use svy regression without subpopulation specification. My logic is whether svy subpopulation works with nldecompose or not(Probably it runs with svy commands only, and not with the svy subpop)?
