WebFeb 17, 2024 · Inference for Distributional Random Forests Confidence intervals for a powerful nonparametric method In a previous article, I extensively discussed the Distributional Random Forest method, a Random Forest-type algorithm that can nonparametrically estimate multivariate conditional distributions. WebBefore we implement a conditional inference tree in R, we will have a look at how decision trees work. We will do this in more detail here as random forests and Boruta analyses are extensions of inference trees and are therefore based on the same concepts.
