coef.GeDSboost,gam: Coef method for GeDSboost, GeDSgam

Description

Methods for the functions coef and coefficients that allow to extract the estimated coefficients of a GeDSboost-class or GeDSgam-class object.

Usage

# S3 method for GeDSboost
coef(object, n = 3L, ...)

# S3 method for GeDSboost coefficients(object, n = 3L, ...)

# S3 method for GeDSgam coef(object, n = 3L, ...)

# S3 method for GeDSgam coefficients(object, n = 3L, ...)

Value

A named vector containing the required coefficients of the fitted multivariate predictor model.

Arguments

object

the GeDSboost-class or GeDSgam-class object from which the coefficients should be extracted.

n

integer value (2, 3 or 4) specifying the order (\(=\) degree \( + 1\)) of the FGB-GeDS/GAM-GeDS fit whose coefficients should be extracted.

  • If n = 2L the piecewise polynomial coefficients of the univariate GeDS base-learners are provided. For bivariate GeDS base-learners, and if class(object) == "GeDSboost", the B-spline coefficients for each iteration where the corresponding bivariate base-learner was selected are provided. For bivariate base-learners, and if class(object) == "GeDSgam", the final local-scoring B-spline coefficients are provided.

  • If n = 3L or n = 4L B-spline coefficients are provided for both univariate and bivariate GeDS learners.

By default n is equal to 3L. Non-integer values will be passed to the function as.integer.

...

potentially further arguments (required by the definition of the generic function). These will be ignored, but with a warning.
