h	R Documentation

h function as defined by Lin et al. (1994).

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

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

`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`.

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

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