Boosted Generalized Linear Classification Learner
mlr_learners_classif.glmboost.Rd
Fit a generalized linear classification model using a boosting algorithm.
Calls mboost::glmboost()
from mboost.
Dictionary
This Learner can be instantiated via the dictionary mlr_learners or with the associated sugar function lrn()
:
