Package: rfVarImpOOB | ||
Title: Unbiased Variable Importance for Random Forests | ||
Version: 1.0 | ||
Date: 2019-03-22 | ||
Version: 1.0.1 | ||
Date: 2020-10-17 | ||
Depends: R (>= 3.2.2), stats, randomForest | ||
Imports: ggplot2, binaryLogic, dplyr,titanic,prob,ggpubr,magrittr | ||
Suggests: knitr,rmarkdown | ||
Author: Markus Loecher <Markus.Loecher@gmail.com> | ||
Maintainer: Markus Loecher <Markus.Loecher@gmail.com> | ||
Description: Computes a novel variable importance for random forests: Impurity reduction importance scores for out-of-bag (OOB) data complementing the existing inbag Gini importance, see also Strobl et al (2007) <doi:10.1186/1471-2105-8-25>, Strobl et al (2007) <doi:10.1016/j.csda.2006.12.030> and Breiman (2001) <DOI:10.1023/A:1010933404324>. | ||
Description: Computes a novel variable importance for random forests: Impurity reduction importance scores for out-of-bag (OOB) data complementing the existing inbag Gini importance, see also <doi: 10.1080/03610926.2020.1764042>. | ||
The Gini impurities for inbag and OOB data are combined in three different ways, after which the information gain is computed at each split. | ||
This gain is aggregated for each split variable in a tree and averaged across trees. | ||
