Discussion

With ‘Fifty Years of Classification and Regression Trees’, Wei-Yin Loh has given a concise historical overview of the central developments in recursive partitioning. It is interesting to read how the successive improvements were triggered by their predecessor algorithms—especially as the author has (co-)authored many of the milestones in our field. Moreover, I appreciate his emphasis on open-source implementations, which make the methodology available to scientists from all disciplines and all around the world
