The bartScoreMargin action computes predictive margins by using a fitted Bayesian additive regression trees (BART) model. Predictive margins are predictions from a model at fixed values of some predictors, averaged over the distribution of the other predictors. This technique is useful for understanding the effect of a specific predictor on the outcome, while accounting for the influence of other variables in the model.
The bartProbit action fits a probit Bayesian Additive Regression Trees (BART) model to data where the response variable is binary. This is particularly useful for classification problems where the outcome is one of two categories (e.g., yes/no, success/failure, 0/1). The probit model assumes that the binary outcome is the result of an unobserved continuous latent variable following a standard normal distribution. The BART model itself is a non-parametric, ensemble method that combines multiple simple regression trees to create a powerful predictive model, offering a flexible alternative to traditional parametric models.
