In fact, I need to compute coefficients,Bayesian statistics turn around the Bayes theorem, which in a regression context is the following: $$ P(theta|Data) propto P(Data|theta) times P(theta) $$ Where (theta) is a set of parameters to be estimated from the data like the slopes and Data is the dataset at hand. 2 Bayesian Inference for Correlation Coefficients 663. MLE chooses the parameters that maximize the likelihood of the data, and is intuitively appealing. Empirical Bayes methods enable the use of auxiliary empirical data, from observations of related parameters, in the development of a Bayes estimator. References appreciated.
