msBP (version 1.4-1)

msBP.nrvTrees: Nesting of the sample through the tree

Description

Compute the path of each subject in the binary tree of weights and returns 3 tree: the n tree, the r tree, and the v tree (see values

Usage

msBP.nrvTrees(sh, maxS = max(sh[,1]))

Value

A list containing tree objects of the class binaryTree. n is the tree containing at each node the number of subjects allocated to that node, r is the tree containing at each node the number of subjects that went right at that node, and v is the tree containing at each node the number of subjects that passed through that node.

Arguments

sh

A matrix with 2 columns and a number of rows equal to the sample size denoting the scale and node labels of each unit

maxS

Upper bound for the scale
