dTTCdtheta_wei function
Description
function of partial derivates of time-to-cure (TTC) by theta (estimated parameters) from a mixture cure model with uncured survival following a Weibull distribution
Usage
dTTCdtheta_wei(
z_ucured = z_ucured,
z_pcured = z_pcured,
theta = theta,
epsilon = epsilon,
TTC
)
Arguments
z_ucured |
covariates matrix acting on survival function of uncured |
z_pcured |
covariates matrix acting on cure proportion |
theta |
estimated parameters from the ouput of a mixture cure model implemented in curesurv |
epsilon |
value fixed by user to estimate the TTC |
TTC |
time-to-cure previously estimated using TTC_wei |
