In survival analysis and other areas, when two or more endpoints are correlated or dependent, the data structure is often modeled via unobserved frailty terms. In this study we review recent research results and conduct sensitivity analyses, both numerically and theoretically, to investigate the influence and outcomes of the frailty specification. We show that its stochastic properties, as well as misspecifications, may impact the inferences on parameter estimates in various ways. Both simulation results and real data analysis are presented for illustration.
