cumLexc_alphaweibull {curesurv} | R Documentation |
cumLexc_alphaweibull function
Description
calculates the cumulative excess hazard from a Weibull distribution
Usage
cumLexc_alphaweibull(
z_ucured = z_ucured,
z_pcured = z_pcured,
x = x,
theta = theta,
sign_delta = 1
)
Arguments
z_ucured |
covariates matrix acting on survival function of uncured |
z_pcured |
covariates matrix acting on cure proportion. |
x |
the time arguments at which to calculate the cumulative excess hazard |
theta |
estimated parameters of the cumulative excess hazard from a mixture model using curesurv and uncured survival following a Weibull distribution |
sign_delta |
only used for mixture cure rate models to specify if the effects or minus the effects of covariates acting on uncured survival to be considered. Default will be sign_delta = "1". The alternative is sign_delta = "-1". |
Value
This object is a list containing the following components:
cumhaz |
cumulative excess hazard estimates |
usurv |
survival of uncured |
SurvE |
net survival estimates |
cured |
cure fraction |
ptcure |
the probability Pi(t) of being cured at a given time t after diagnosis knowing that he/she was alive up to time t. |
