Estimate restricted mean survival time (RMST) based on Cox regression model

Estimate restricted mean survival time (RMST) based on Cox regression model

Usage

cox.rmst(y, d, x.cate, xnew, tau0)

Arguments

y

Observed survival or censoring time; vector of size n.

d

The event indicator, normally 1 = event, 0 = censored; vector of size n.

x.cate

Matrix of p.cate baseline covariates specified in the outcome model; dimension n by p.cate.

xnew

Matrix of p.cate baseline covariates for which we want an estimate of the RMST; dimension m (observations in the new data set) by p.cate

tau0

The truncation time for defining restricted mean time lost.

Value

The estimated RMST for new subjects with covariates xnew; vector of size m.
