[R] Residual plots and residual deviance in the SURVEY package when only 'working deviance' available

Hello -

I am analysing some survey data using the svyglm() command in the survey package. Since I am doing binomial regression, the family I'm choosing is 'quasibinomial', since this suppresses the warning that comes about from the inclusion of non-integer outcomes due to weights.

I am looking at doing some proper diagnostics of my model. However, the only goodness-of-fit method I can see from the mailing list is regtermtest(), which essentially tests the significance of additional terms, or the hypothesis that the model is better than the intercept.

My questions are:

- is it possible to obtain residual 'working' deviance after the Rao-Scott method, which would indicate deviance with respect to the saturated model?

- by way of corrollary (or substitute), can deviance residuals be obtained?

- given that svyglm appears to give the raw residuals through the residuals([svyglm object]) command, does anyone know of a good reference on how to effectively use pearson residuals for model diagnostics (on the basis that deviance ones are unavailable).

Many thanks.
