Description: Simulate survival times from standard parametric survival
        distributions (exponential, Weibull, Gompertz), 2-component
        mixture distributions, or a user-defined hazard, log hazard,
        cumulative hazard, or log cumulative hazard function. Baseline
        covariates can be included under a proportional hazards
        assumption. Time dependent effects (i.e. non-proportional
        hazards) can be included by interacting covariates with linear
        time or a user-defined function of time. Clustered event times
        are also accommodated. The 2-component mixture distributions
        can allow for a variety of flexible baseline hazard functions
        reflecting those seen in practice. If the user wishes to
        provide a user-defined hazard or log hazard function then this
        is possible, and the resulting cumulative hazard function does
        not need to have a closed-form solution. For details see the
        supporting paper <doi:10.18637/jss.v097.i03>. Note that this
        package is modelled on the 'survsim' package available in the
        'Stata' software (see Crowther and Lambert (2012)
        <https://www.stata-journal.com/sjpdf.html?articlenum=st0275> or
        Crowther and Lambert (2013) <doi:10.1002/sim.5823>).
