      Then, the joint distribution is derived using a marginal distribution of the continuous outcomes and the conditional distribution of the latent variables (given the continuous variables) underlying the binary/ordinal outcomes. This approach is referred to as the conditional grouped continuous model (CGCM) by De Leon and Chough (2013).

      Comment: If p - g = 1, i.e. if the subset consists of a single independent variable, then this F-test is equivalent to the two-sided t-test presented in Part II. In fact, t2 = F. You might recall a similar result from simple regression analysis. Text Reference: Section 2.8. I’m extending the concept to multiple regression. Example Application

      Bayesian learning methods are relevant to study of machine learning for two different reasons. First, Bayesian learning algorithms that calculate explicit probabilities for hypotheses, such as the naive Bayes classifier, are among the most practical approaches to certain types of learning problems.
