%description
Provides a random forest based implementation of the method described in
Chapter 7.1.2 (Regression model based anomaly detection) of Chandola et
al. (2009) <doi:10.1145/1541880.1541882>. It works as follows: Each
numeric variable is regressed onto all other variables by a random forest.
If the scaled absolute difference between observed value and out-of-bag
prediction of the corresponding random forest is suspiciously large, then
a value is considered an outlier. The package offers different options to
replace such outliers, e.g. by realistic values found via predictive mean
matching. Once the method is trained on a reference data, it can be
applied to new data.
