varest2: Variance estimate with sandwich formula based on the EM...

In geecure: Marginal Proportional Hazards Mixture Cure Models with Generalized Estimating Equations

Description

Calculate the variance estimates using the sandwich formula based on the EM algorithm.

Usage

varest2(Time, Status, X, Z, id, gamma, beta, bsurv, w)

Arguments

Time	right censored data which is the follow up time.
Status	the censoring indicator, normally 0 = event of interest happens, and 0 = censoring.
X	a matrix of covariates corresponding to the latency part.
Z	a matrix of covariates corresponding to the incidence part.
id	a vector which identifies the clusters. The length of id should be the same as the number of observations.
gamma	the estimates for the incidence part.
beta	the estimates for the latency part.
bsurv	the estimate of the baseline survival function for the latency part.
w	conditional probability of a patient remains uncured.
