predcall_tneh: predcall_tneh function

Description

calculates the predicted cure indicators from a Time to null excess hazard model.

Usage

predcall_tneh(
  object,
  pred,
  z_tau = z_tau,
  z_alpha = z_alpha,
  x = x,
  xmax = NULL,
  level = level,
  epsilon = epsilon,
  cumLexc_topred
)

Arguments

object: ouput from a model implemented in curesurv
pred: some predicted estimates
z_tau: Covariates matrix acting on time-to-null parameter.
z_alpha: Covariates matrix acting on parameter alpha of the density of time-to-null excess hazard model
x: time at which the predictions are provided
xmax: time max at which Pi(t) is calculated.
level: (1-alpha/2)-order quantile of a normal distribution
epsilon: value fixed by user to estimate the \(\text{Pi}(t)\geq (1-\epsilon)\). By default \(\epsilon = 0.05\).
cumLexc_topred: pre prediction obtained either from cumLexc_adtneh2_topred or cumLexc_mul_topred
