Dear Statalist,
I am doing multinomial regression using data that has been
svyset. Have I correctly interpreted
Hosmer and Lemeshow's "Applied Logistic Regression" (p 219-20) in
understanding that a legitimate
approach is to ignore the survey design when comparing models (i.e.,
when using fitstat in SPost)
by running the models without the svy command, use the commands such
as fitstat to aid in selection
of a final model, and then run the final model with the svy command
to obtain more accurate standard
errors?
I suspect that nothing too horrible will happen if you do that, but
it is hard to say. If the models are nested though, you can just use
the test command, e.g.
webuse nhanes2f
svy: mlogit health female black rural age
test rural age
