Description: 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,
        Jorgensen-Seshadri-Whitmore, weighted Akash, weighted Shanker
        and weighted Sujatha 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)
