BART: Bayesian Additive Regression Trees
www-stat.wharton.upenn.eduposterior. Efiectively, BART is a nonparametric Bayesian regression approach which uses dimensionally adaptive random basis elements. Motivated by ensemble methods in general, and boosting algorithms in particular, BART is deflned by a statistical model: a prior and a likelihood. This approach enables full posterior inference including point

Lecture 5 Hypothesis Testing in Multiple Linear Regression
courses.washington.eduThe regression sums of squares due to X2 when X1 is already in the model is SSR(X2|X1) = SSR(X)−SSR(X1) with r degrees of freedom. This is also known as the extra sum of squares due to X2. SSR(X2|X1) is independent of MSE. We can test H 0: β2 = 0 with the statistic F 0 = SSR(X2|X1)/r MSE ∼ F r,n−p−1.
