In shatteringdt: Provide SLT Tools for 'rpart' and 'tree' to Study Decision Trees

Description

Using a recursion, calculates the shattering coefficient for a rpart decision tree.

Usage

recurse(nodes, left, right, node, parent, samples, node_type, shattering, n_samples)

Arguments

nodes	list. A list containing the tree nodes.
left	int. The left child of the parent node.
right	int. The right child of the parent node.
node	int. The current node being analyzed
parent	int. The parent node of node.
samples	list. The number of dataset samples for each node of the tree.
node_type	string. The type of the node, e.g., leaf if it's a leaf node.
shattering	float. The shattering coefficient that are begin computed.
n_samples	int. The # of samples to consider in dataset.

Value

The calculus of the shattering coefficient.
