Hi (James)
I was wanting to clarify the following statement about testing model fit and survey data, as I am new to the area

>> The usual techniques of adding interactions and testing augmented against reduced models also apply.
If I try the following (after svysetting the data)
svy: logistic outcome varA
estat stor A
svy: logistic outcome varA varB
estat stor B
lrtest A B
I get the message:
lrtest is not appropriate with survey estimation results
What would be the most appropriate method(s) to compare reduced and agumented models? I have a Number of categorical and interaction terms to consider.
Thanks for your advice
Ron
