Web22 de abr. de 2024 · The coefficient of determination ( R ²) measures how well a statistical model predicts an outcome. The outcome is represented by the model’s dependent variable. The lowest possible value of R ² is 0 and the highest possible value is 1. Put simply, the better a model is at making predictions, the closer its R ² will be to 1. WebBayes Rule. The cornerstone of the Bayesian approach (and the source of its name) is the conditional likelihood theorem known as Bayes’ rule. In its simplest form, Bayes’ Rule states that for two events and A and B (with P(B) ≠ 0 ): P(A B) = P(B A)P(A) P(B) Or, if A can take on multiple values, we have the extended form:
