The 'nBI' parameter sets the number of burn-in iterations (default 100) which are discarded. The 'nMC' parameter sets the number of subsequent MCMC iterations that are saved for prediction (default 1000).

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.
