  • Blagojevic, Milica; MacKenzie, Gilbert; Do Ha, II (IWSM, 2003)
    The non-PH Canonical Time Dependent Logistic survival regression model described by MacKenzie (1996, 2002), is extended by incorporating a multiplicative Gamma frailty component into the hazard function. The resulting model ...
  • MacKenzie, Gilbert; Do Ha, II (IWSM, 2007)
    We revisit the crossing hazards problem in survival analysis and compare the use of Cox's semi-parametric model with a parametric non-PH model from the generalised time-dependent logistic family(GTDL). A set of gastric ...
  • 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) ...
  • Do Ha, II; MacKenzie, Gilbert (SAGE Publications, 2010)
    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 ...
  • MacKenzie, Gilbert; Do Ha, II (IWSM, 2013)
    The focus is mainly, but, not solely, on longitudinal randomised controlled clinical trials. The paper aims to delineate the role of frailty in the modern analysis of such trials and also in longitudinal survival studies. ...
