WebbFunction to assess the optimal number of boosting trees using k-fold cross validation. This is an implementation of the cross-validation procedure described on page 215 of Hastie et al (2001). The data is divided into 10 subsets, with stratification by prevalence if required for presence/absence data. The function then fits a gbm model of increasing complexity … WebbAn estimator object that is used to compute the initial predictions. init has to provide fit and predict_proba.
