Proportional odds frailty model and stochastic comparisons

Gupta, Ramesh; Peng, Cheng - In: Annals of the Institute of Statistical Mathematics 66 (2014) 5, pp. 897-912

In this paper, we present some distributional properties of the survival and frailty distribution involved in the proportional odds (PO) frailty model. Stochastic orderings are studied for this proportional odds frailty model. It is showed that negative dependence arises in the PO frailty model...
