SVC_selection {varycoef}

SVC Model Selection

Description

This function implements the variable selection for Gaussian process-based SVC models using a penalized maximum likelihood estimation (PMLE, Dambon et al., 2021, <arXiv:2101.01932>). It jointly selects the fixed and random effects of GP-based SVC models.

Usage

SVC_selection(obj.fun, mle.par, control = NULL, ...)

Arguments

obj.fun

(SVC_obj_fun)
Function of class SVC_obj_fun. This is the output of SVC_mle with the SVC_mle_control parameter extract_fun set to TRUE. This objective function comprises of the whole SVC model on which the selection should be applied.

mle.par

(numeric(2*q+1))
Numeric vector with estimated covariance parameters of unpenalized MLE.

control

(list or NULL)
List of control parameters for variable selection. Output of SVC_selection_control. If NULL is given, the default values of SVC_selection_control are used.

...

Further arguments.

Value

Returns an object of class SVC_selection. It contains parameter estimates under PMLE and the optimization as well as choice of the shrinkage parameters.
