%description
An implementation of extensions to Freund and Schapire's AdaBoost
algorithm and Friedman's gradient boosting machine. Includes regression
methods for least squares, absolute loss, t-distribution loss, quantile
regression, logistic, multinomial logistic, Poisson, Cox proportional
hazards partial likelihood, AdaBoost exponential loss, Huberized hinge
loss, and Learning to Rank measures (LambdaMart). Originally developed by
Greg Ridgeway. Newer version available at github.com/gbm-developers/gbm3.
