hyperprior distributions for hyperparametric models what is the distribution of the concentrations in a dirichlet model that is always positive? how to model concentration parameters what is the hyperprior distribution can dirichlet hyperprior be fixed can a multinomial dirichlet model use hyperprior distribution gamma hyperprior can a multinomial dirichlet model have hyper prior distribution what is hyperprior distribution can you model concentration as a hyperprior distribution how to use hyperprior distribution in the mdd model what is the hyperprior distribution which parameter follows a dirichlet prior distribution? how to impose hyperprior distribution can you use hyperprior distribution in gamma what is the hyperprior distribution for gamma can gamma hyperprior be used with a categorical model what kind of distribution is an hgp distribution how do you model hyper prior what is the distribution of a dirichlet prior variable?
