WebOct 14, 2024 · Similar to the Bayesian binary logistic regression model, we can use the PPPS and Bayes factor (which are not discussed in this tutorial) to evaluate the fit of a Bayesian binomial logistic regression model. Correct classification rate and AUC are not suited here, as the model is not concerned with classification. WebIf the prior distribution is beta, and the likelihood is binomial, then the posterior predictive distribution is a beta-binomial distribution.

WebApr 8, 2024 · The Beta-Binomial Bayesian Model With more data generating day by day, I believe Bayesian statistics is the way to go. That's why I'm writing this series of posts on Bayesian statistics. In this post, I'll introduce the Beta-Binomial Bayesian model again. I'll also show how two communities (Python and R) have implemented this model. WebBayesian hierarchical modelling is a statistical model written in multiple levels (hierarchical form) that estimates the parameters of the posterior distribution using the Bayesian method. The sub-models combine to form the hierarchical model, and Bayes' theorem is used to integrate them with the observed data and account for all the uncertainty that is present.
