A data scientist specifies PROC HPSPLIT with a GROW ENTROPY option. What splitting criterion does this select?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — b is correct because GROW ENTROPY in PROC HPSPLIT selects the information gain criterion, which uses Shannon entropy to measure impurity and chooses the split that maximally reduces entropy (maximizes information gain). A (Gini) is the default (GROW GINI).

Full Explanation
B is correct because GROW ENTROPY in PROC HPSPLIT selects the information gain criterion, which uses Shannon entropy to measure impurity and chooses the split that maximally reduces entropy (maximizes information gain). A (Gini) is the default (GROW GINI). C (chi-square) is used in CHAID-style trees with GROW CHISQ. D (variance reduction) is used for regression targets and is not invoked by ENTROPY.
