cumLexc_alphaweibull_topred: cumLexc_alphaweibull_topred function

Description

calculates the cumulative excess hazard from a Weibull distribution

Usage

cumLexc_alphaweibull_topred(
  z_ucured = z_ucured,
  z_pcured = z_pcured,
  x = x,
  theta = theta,
  sign_delta = 1
)

Value

This object is a list containing the following components:

cumhaz

cumulative excess hazard estimates

usurv

survival of uncured

SurvE

net survival estimates

cured

cure fraction

pt_cure

the conditionnal probability of being cured knowing they are alive at t

Arguments

z_ucured

covariates matrix acting on survival function of uncured

z_pcured

covariates matrix acting on cure proportion.

x

the time arguments at which to calculate the cumulative excess hazard

theta

the parameters of the cumulative excess hazard from a Weibull distribution

sign_delta

only used for mixture cure rate models to specify if the effects or minus the effects of covariates acting on uncured survival to be considered. Default will be sign_delta = "1". The alternative is sign_delta = "-1".
