The only video on the entire internet that made sense regarding DT, i completely built a CHAID DT from the scratch and on the way you explained everything like a charm, it was more like DT for dummies. Please Mr. Meyer can you please cover C5.0, C&RT and QUEST algorithms aswell? A very prosperous new year ahead.

My understanding is that rpart is an implementation of the CART [Classification and Regression Tree]. Not CHAID.
