Bayesian Analysis of Bivariate Competing Risks Models
Absolutely continuous bivariate exponential (ACBVE) models have been widely used in the analysis of competing risks data involving two risk components. For such an analysis, frequentist approach often runs into difficulty due to a likelihood containing some nonidentifiable parameters. With an end to overcome this nonindentifiability, we consider Bayesian procedures. Utilization of informative p...
متن کاملIdentifiability of bivariate frailty models
Frailty models are used in survival analysis to account for unobserved heterogeneity in individual risks to disease and death. To analyze bivariate data on related survival times (e.g. matched pairs experiments, twin or family data), bivariate correlated frailty models were suggested, where the frailties were constructed using independent additive components. The purpose of this paper is to des...
متن کاملThe Identifiability Problem for Repairable Systems Subject to Competing Risks
Within reliability theory, identifiability problems arise through competing risks. If we have a series system of several components, and if that system is replaced or repaired to as good as new on failure, then the different component failures represent competing risks for the system. It is well known that the underlying component failure distributions cannot be estimated from the observable da...
متن کاملApproximation of bivariate copulas by patched bivariate Fréchet copulas
Bivariate Fréchet (BF) copulas characterize dependence as a mixture of three simple structures: comonotonicity, independence and countermonotonicity. They are easily interpretable but have limitations when used as approximations to general dependence structures. To improve the approximation property of the BF copulas and keep the advantage of easy interpretation, we develop a new copula approxi...
