  • Blagojevic, Milica; MacKenzie, Gilbert (IWSM, 2007)
    The non-PH Canonical Time Dependent Logistic (CTDL) survival re- gression model is extended by incorporating a positive stable frailty component into the hazard function within the Bayesian framework. The resulting model ...
  • MacKenzie, Gilbert; Lee, Youngjo (IWSM, 2006)
    Frailty models are now widely used for analyzing multivariate survival data. An open question is how best to determine how to select the most appropriate frailty structure supported by the data. Herein, we develop a ...
  • MacKenzie, Gilbert; Do Ha, II; Lee, Youngjo (IWSM, 2003)
    Correlated survival times may be modelled by introducing a random effect, or frailty, component into the hazard function. For multivariate survival data we extend a non-PH model, the generalized time-dependent logistic (GTDL) ...
  • Blagojevic, Milica; MacKenzie, Gilbert (IWSM, 2004)
    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 ...

    Correlated survival times can be modelled by introducing a random effect, or frailty component, into the hazard function. For multivariate survival data we extend a non-PH model, the generalized time-dependent logistic ...
