We generalize the previously developed Non-PH CTDL-Gamma and
the PH Weibull-Gamma frailty models to correlated survival data. In particular,
we seek analytical results using the marginal approach, to determine whether the
univariate results generalize to the multivariate context. We consider both the
shared and correlated frailty cases.We also develop non-parametric frailty models
which enable us to check the appropriateness of the assumed distributional form
of the random effect.
