The Dirichlet-multinomial model is the generalization of the beta-binomial model to multiple (more than 2) classes or categories. This model has a wide scope of applications in which the focus is to analyze data from rates of multiple distinct outcomes. In this work, we study the sensitivity of the posterior distribution of a Dirichlet-multinomial model to the main Dirichlet objective priors of the literature.
