The power prior is a useful
informative prior in Bayesian inference. However, for model selection or model
comparison problems, the propriety of the power prior is one of the critical
issues. In this paper, we focus on the propriety of the joint power prior and
derive the necessary conditions for the propriety of the Weibull regression
model.
