Researchers have developed new strategies to enhance Probabilistic Regression Trees (PRTrees) by directly handling missing predictor values during tree construction. This approach eliminates the need for pre-imputation and preserves the core probabilistic properties of the model. Evaluations on real-world datasets indicate that these methods can outperform traditional regression trees like CART, especially when dealing with significant amounts of missing data, while retaining the interpretability of tree-based models.
