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

coefficients(object, n = 3L, ...)
A named vector containing the required coefficients of the fitted multivariate predictor model.
the GeDSboost-class
or
GeDSgam-class
object from which the coefficients should be
extracted.
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.
