regfun {incidental}

Beta regularization function

Description

This function computes regularization penalty term based on the betas and a difference.

Usage

regfun(beta, regularization_order = 2)

Arguments

beta

A spline parameter vector length num_params.

regularization_order

An integer (typically 0, 1, 2), indicating differencing order for L2 regularization of spline parameters. Default is 2 for second derivative penalty.

Value

A scalar regularization value.
