Web8 sep. 2015 · The package rpart does not do this, it instead computes a surrogate split on the height variable, height > 3.5. The idea behind this is as follows: Weight is obviously the best variable to split on. However, when Weight is missing, a split using Height is a good approximation to the split otherwise obtained using Weight.
