oob.error.rate

oob.error.rate.wsrf

Return out-of-bag error rate for "<code>wsrf</code>" model.

A parallel implementation of Weighted Subspace Random Forest. The
Weighted Subspace Random Forest algorithm was proposed in the
International Journal of Data Warehousing and Mining by Baoxun Xu,
Joshua Zhexue Huang, Graham Williams, Qiang Wang, and Yunming Ye
(2012) <DOI:10.4018/jdwm.2012040103>. The algorithm can classify
very high-dimensional data with random forests built using small
subspaces. A novel variable weighting method is used for variable
subspace selection in place of the traditional random variable
sampling.This new approach is particularly useful in building
models from high-dimensional data.

<dd>object of class <code>wsrf</code>.</dd>
 <dt>tree</dt>
<dd>logical or an integer vector for the index of a specific
 tree in the forest model. If provided as an integer vector,
 <code>oobErrorRate.wsrf</code> will give the corresponding out-of-bag
 error rates of the exact trees specified by <code>tree</code>. If TRUE,
 all error rates will be presented. If FALSE or missing, the gross
 error rate for the forest will be given.</dd>
