bigctree-class: Classification Trees in Random Forests

Description

Class representing a tree in a classification random forest.

Arguments

Objects from the Class

Objects can be created by calls of the form new("bigctree", ...), but most often are generated when building a bigcforest using bigrfc.

Slots

insamp:
Object of class "integer". Number of times each training example is in the bag for this tree.
inweight:
Object of class "numeric". Sum of class weights for each in-bag example.
nnodes:
Object of class "integer". Number of nodes in the tree.
treemap:
Object of class "matrix". Indices of tree nodes. For a given node n, treemap[n, ] represents the indices of the left and right children. If a node is terminal, then both elements of treemap[n, ] are 0.
nodeclass:
Object of class "integer". Majority class of each terminal node.
nodewt:
Object of class "numeric". Sum of class weights of the examples in each terminal node.
bestvar:
Object of class "integer". Best variable that each node was split on, or 0 for terminal nodes.
bestnumsplit:
Object of class "numeric". Split point for nodes split on a numerical variable.
bestcatsplit:
Object of class "list". Split point, expressed as integer vectors indicating which factor levels to split on, for nodes split on a categorical variable.
termincount:
Object of class "numeric". Number of training examples in each terminal node.
trainprednode:
Object of class "integer". Terminal node number for each training example.
trainpredclass:
Object of class "integer". Class of terminal node for each training example.
tgini:
Object of class "numeric". Total gini.
