Fit a shared gamma frailty model and Cox proportional hazards model using a Penalized Likelihood on the hazard function. Left truncated, censored data and strata (max=2) are allowed. Clustered and recurrent survival times can be studied (the Andersen-Gill (1982) approach has been implemented for recurrent events). An automatic choice of the smoothing parameter is possible using an approximated cross-validation procedure.
