Description
The trace of the hat matrix corresponds to the effective degrees of freedom (edf) of a generalized additive model. The edf is used as an internal measure of model complexity.
Usage
1
calcTrA(W, X, lambda=0)
Arguments
W
Weight matrix of the pseudo iterated least squares algorithm. See function calcWdiag
X
Design matrix of the covariates.
lambda
Regularization parameter of kernel ridge regression.
Value
Effective degrees of freedom of a generalized additive model with regularization (numeric scalar).
Note
This function is not intended to be called directly by the user. Should only be used by experienced users, who want to customize the model.
