WGT.CEN: Calculate the censoring weights

In michellezhou2009/NCCIPW: NCCIPW

Calculate the censoring weights

Description

Calculate the weights accounting for missing binary outcomes due to censoring.

Usage

WGT.CEN(Ti, Di, t0, Vii.ptb = NULL)

Arguments

Ti	a vector of censored event times.
Di	a vector of binary values (1 or 0) indicating whether the true event time is observed.
t0	a numerical value which is the prediction time period, used for creating the binary outcome status. The value is 1 if the event time is smaller than t0; otherwise, it is 0.
Vii.ptb	a vector of perturbation variables. The default is NULL if the perturbation procedure is not implemented for estimating the variance of the IPW estimators.

Value

If Vii.ptb=NULL, it returns a single-column matrix which includes the censoring weights; otherwise, it returns a matrix with the first column being the censoring weights and the remaining columns being their perturbed counterparts.
