Computing residuals and predicted values using "logit.survey" and "weights" in Zelig R package

by Barankanira Emmanuel

Dear Users, I'm using the Zelig package in R to predict the HIV prevalence. In others words, I want to estimate the model that regresses the HIV status (HIV+ or HIV-) on the sex (male, female). I have a problem of getting the residuals and the predicted values of the models with and without covariates respectively : resu1 <- zelig(HIV~1,model = "logit.survey",weights = ~Weight,data=PREVATOUT) resu2 <- zelig(HIV~Sex,model = "logit.survey",weights = ~Weight,data=PREVATOUT) where HIV is a dichotomous indicator (HIV=0 or HIV=1), Weight is the survey sampling weight, Sex (Sex=1 for men and Sex=2 for female) and PREVATOUT is my dataset containing other covariates. How can I get the residuals and the predicted values of the models? Any idea? Thanks. *************************************** Emmanuel BARANKANIRA Phone : (+33)623575806 E-mail : baremma2002(a)yahoo.fr France ***************************************
