tau_proc {tauProcess}

Estimate the Tau Process with/without cure fraction

Description

Estimate the Tau Process with/without cure fraction

Usage

tau_proc(data, t = NULL, cure = FALSE)

Arguments

data

a data.frame consisting of arm, surv.time, event.

t

a sequence of specified times. If the user do not specify the sequence, the default is an equally-spaced sequence from 0 to the last identified time.

cure

a boolean variable indicating whether to consider the cure fractions.

Details

The estimation method proposed by Yi-Cheng Tai, Weijing Wang and Martin T. Wells to estimate tau process with or without cure fraction.

Value

an object of class "tau_process" with components

t	the specified sequence of time points
vals_tau_proc	the estimated value of tau measure at given time
cure	a boolean variable indicating whether to consider the cure fraction
cure_rates	the estimated cure rates for Group 0 and Group 1, respectively

Examples

tau_proc(data = pbc)
