Hello
I am analysing survey data with probability weights applied.  I want to compare simple with complex logistic regression models.  Normally I would save estimates from the complex model using the 'estimates store' command, and then  consider the simple model to be nested in the complex model.  I would then run the likelihood ratio test with the 'lrtest' command.
However, I cannot do this with p-weighted data.  I could use the 'force' command but the help menu advises against this.  
Is there an alternative way to compare two logistic regression models using the p-weighted data?
Thanks.
