baseline: calculating baseline hazard and baseline cumulative hazard...

In surtvep: Cox Non-Proportional Hazards Model with Time-Varying Coefficients

calculating baseline hazard and baseline cumulative hazard using the result from a coxtv or coxtp object

Description

The baseline estimation is the baseline hazard at each observed failure time when holding all the covariates to be zero.

Usage

baseline(fit)

Arguments

fit	model from coxtv or coxtp.

Value

A list with three components:

time	the unique observed failure times.
hazard	the baseline hazard corresponding to each unique failure time point.
cumulHaz	the cumulative baseline hazard corresponding to each unique failure time point.

Examples

data(ExampleData)
z <- ExampleData$z
time  <- ExampleData$time
event <- ExampleData$event

fit   <- coxtv(event = event, z = z, time = time)
base.est <- baseline(fit)
