Bivariate Frailty Model and Association Measure



In this paper, we present a bivariate frailty model and the association measure. The relationship between the conditional and the unconditional hazard gradients are derived and some examples are provided. A correlated frailty model is presented and its application in the competing risk theory is given. Some applications to real data sets are also pointed out.
