Fit the logistic model in the incidence part with the GEE approach
geega(w, Z, gamma, id, corstr)conditional probability of a patient remains uncured at the mth iteration. We use Status as initial value.
a matrix of covariates corresponding to the incidence part.
initial beta for the GEE for the latency part. We use 0 as the initial value.
a vector which identifies the clusters. The length of id should be the same as the number of observations.
a character string specifying the correlation structure. The following are permitted: independence and exchangeable.
