Description

An internal function meant only to be used by the covariance function.

Usage

1
h(t_i, delta_i, beta, time, z, S0_i, S1_i)

Arguments

t_i

The follow up times.

delta_i

Indicator that the individual was censored: 1 if the individual was censored, 0 otherwise.

beta

The coefficients of the Cox model.

time

Survival time.

z

Covariates for survival time.

S0_i

Object described in Lin et al. (1994), slightly modified for computationnal efficiency. It is obtained with function1.

S1_i

Object described in Lin et al. (1994), slightly modified for computationnal efficiency. It is obtained with function1.

Details

This is an internal function, only meant to be used by the covariance function.

Value

A numeric value described in Lin et al. (1994).
