%description
The oblique decision tree (ODT) uses linear combinations of predictors as
partitioning variables in a decision tree. Oblique Decision Random Forest
(ODRF) is an ensemble of multiple ODTs generated by feature bagging. Both
can be used for classification and regression as supplements to the
classical CART of Breiman (1984) <DOI:10.1201/9781315139470> and Random
Forest of Breiman (2001) <DOI:10.1023/A:1010933404324> respectively.
