extrafrail: Estimation and Additional Tools for Alternative Shared Frailty
Models
Provide estimation and data generation tools for new multivariate frailty models.
This version includes the gamma, inverse Gaussian, weighted Lindley, Birnbaum-Saunders,
truncated normal, mixture of inverse Gaussian, mixture of Birnbaum-Saunders,
generalized exponential and Jorgensen-Seshadri-Whitmore as the distribution for
frailty terms. For the basal model, it is considered a parametric approach based
on the exponential, Weibull and the piecewise exponential distributions as well as a
semiparametric approach. For details, see Gallardo et al. (2024) <doi:10.1007/s11222-024-10458-w>,
