演講題目：Flexible bivariate Beta models and their close relatives
A spectrum of bivariate Beta models will be considered. A variety of construction strategies are utilized including: trivariate reduction, copula based modeling, conditionally specified models, conditional survival models, and construction of a broad class of flexible models involving independent Gamma distributed components. Close relatives of such bivariate Beta models include bivariate generalized Beta models as well as bivariate Pareto and Kumaraswamy models. Likelihood and Bayesian inference strategies can be employed with little difficulty in simplified sub-models, and with more difficulty in the most general cases.
