Description Usage Arguments Details Value Author(s)

Description

Probability density, distribution, quantile, random generation, hazard cumulative hazard, mean, and restricted mean functions for generic non-mixture cure models. These distribution functions take as arguments the corresponding functions of the base distribution used.

Value

dnmixsurv gives the density, pnmixsurv gives the distribution function, hnmixsurv gives the hazard and Hnmixsurv gives the cumulative hazard.

qnmixsurv gives the quantile function, which is computed by crude numerical inversion.

rnmixsurv generates random survival times by using qnmixsurv on a sample of uniform random numbers. Due to the numerical root-finding involved in qnmixsurv, it is slow compared to typical random number generation functions.

mean_nmixsurv and rmst_nmixsurv give the mean and restricted mean survival times, respectively.
