dlogTTCdtheta_wei: dlogTTCdtheta_wei function

In curesurv: Mixture and Non Mixture Parametric Cure Models to Estimate Cure Indicators

dlogTTCdtheta_wei function

Description

function of partial derivates of log of time-to-cure log(TTC) by theta (estimated parameters) from a mixture cure model with uncured survival following a Weibull distribution

Usage

dlogTTCdtheta_wei(
  z_ucured = z_ucured,
  z_pcured = z_pcured,
  object = object,
  epsilon = epsilon,
  TTC
)

Arguments

z_ucured	covariates matrix acting on survival function of uncured
z_pcured	covariates matrix acting on cure proportion
object	ouput from a model implemented in curesurv
epsilon	value fixed by user to estimate the TTC \text{Pi}(t)\geq (1-\epsilon). By default \epsilon = 0.05.
TTC	time to cure previsouly estimated by TTC_wei
