dlogsndtheta_wei: dlogsndtheta_wei function

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

dlogsndtheta_wei function

Description

function of partial derivates of log of net survival depending on theta (estimated parameters) from a mixture cure model with uncured survival following a Weibull distribution

Usage

dlogsndtheta_wei(
  z_ucured = z_ucured,
  z_pcured = z_pcured,
  x = x,
  theta = theta,
  cumLexctopred
)

Arguments

z_ucured	covariates matrix acting on survival function of uncured
z_pcured	covariates matrix acting on cure proportion
x	time at which the estimates are predicted
theta	estimated parameters from the ouput of a mixture cure model implemented in curesurv
cumLexctopred	a pre-prediction parameter obtained with cumLexc_alphaweibull_topred
