Arguments

object

objects of class glmboost, gamboost or gbAIC.

x

objects of class glmboost or gamboost.

newdata

optionally, a data frame in which to look for variables with which to predict.

type

a character indicating whether the fit or the response (classes) should be predicted in case of classification problems.

allIterations

computes the (linear) predictor for all boosting iterations simultaneously and returns a matrix.

method

a character specifying if the corrected AIC criterion or a classical (-2 logLik + k * df) should be computed. df{ a character specifying how degrees of freedom should be computed: trace
