## Is there any function that calculates Gini Index for CART

Decision Tree Learning Univerzita Karlova. This process of top-down induction of decision trees (tdidt) is an example of a greedy algorithm, gini impurity used by the cart, gini index. gini index is a metric for classification tasks in cart. it stores sum of squared probabilities of each class. we can formulate it as illustrated below..
