st: Residuals in svy:intreg

Dear Statalisters,

I'm working with Stata 9.2 for Windows.

I have to carry out an interval regression with survey data, because
there are top and bottom censored values. I've noticed Stata version
9.2 does not provide residuals for this model. It calculates predicted
values, but if it does not provide (observed-predicted values), there
must be a good reason.

I understand that, because I'm in a survey environment, I do not have
to check for homoskedasticity of residuals and that they are not
expected to be independent. But residuals would still be useful to
check for model lack of fit (nonlinearity and presence for influential
points and outliers). Do you know of any alternatives?

Thank you very much.

Angel Rodriguez-Laso
