curesurv (version 0.1.1)

pt_cure_ic_wei: pt_cure_ic_wei function

Description

Calculates the confidence intervals of the probability Pi(t) of being cured at a given time t after diagnosis knowing that he/she was alive up to time t. by Delta Method on P(t)

Usage

pt_cure_ic_wei(
  object,
  z_pcured = z_pcured,
  z_ucured = z_ucured,
  x,
  level,
  cumLexctopred,
  Dpt_cure
)

Arguments

object
