discfrail (version 0.2)

Cox Models for Time-to-Event Data with Nonparametric Discrete Group-Specific Frailties

Description

Functions for fitting Cox proportional hazards models for grouped time-to-event data, where the shared group-specific frailties have a discrete nonparametric distribution. The methods proposed in the package is described by Gasperoni, F., Ieva, F., Paganoni, A. M., Jackson, C. H., Sharples, L. (2018) . There are also functions for simulating from these models, with a nonparametric or a parametric baseline hazard function.
