%description
Fast OpenMP parallel computing of Breiman's random forests for univariate,
multivariate, unsupervised, survival, competing risks, class imbalanced
classification and quantile regression. New Mahalanobis splitting for
correlated outcomes.  Extreme random forests and randomized splitting.
Suite of imputation methods for missing data.  Fast random forests using
subsampling. Confidence regions and standard errors for variable
importance. New improved holdout importance. Case-specific importance.
Minimal depth variable importance. Visualize trees on your Safari or
Google Chrome browser. Anonymous random forests for data privacy.
