(i.e. ``subsample < 1.0``), the estimates are derived from the improvement in loss based on the examples not included in the bootstrap sample (the so-called out-of-bag examples). The OOB estimator is ...

for Gradient Boosting. The example is taken from Hastie et al 2009 [1]_. The loss function used is binomial deviance. Regularization via shrinkage (``learning_rate < 1.0``) improves performance ...
