Predict from Saved Trees — predict

Generate predictions for new data using saved tree structures from a prince_bart fit.

Usage

predict_trees(trees, newdata, scaling = NULL, n_cores = 1)

trees: A data.frame of tree structures from a prince_bart fit.
newdata: A matrix of covariates for prediction (can be unscaled if scaling is provided), or a list of matrices (one per posterior sample).
scaling: Optional list with center and scale named vectors for standardizing newdata before prediction. Typically from prince_bart_fit$scaling. If NULL, newdata is assumed to already be scaled.
n_cores: Number of cores for parallel prediction (default: 1).

A matrix of predicted probabilities with rows for observations and columns for posterior samples.
