Specification of Informative Prior Distributions for Multinomial Models Using Vine Copulas

[摘要] We consider the specification of an informative prior distribution for the probabilities in a multinomial model. We utilise vine copulas: flexible multivariate distributions built using bivariate copulas stacked in a tree structure. We take advantage of a
