Description
Estimation and Additional Tools for Alternative Shared Frailty Models.
Description
Provide estimation and data generation tools for some new multivariate frailty models. This version includes the gamma, inverse Gaussian, weighted Lindley, Birnbaum-Saunders, truncated normal, mixture of inverse Gaussian and mixture of Birnbaum-Saunders as the distribution for the 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 and Bourguignon (2022) <doi:10.48550/arXiv.2206.12973> and Gallardo et al. (2024) <doi:10.1007/s11222-024-10458-w>.
