Extracting a New Formula After Selection Algorithms

Description

The generic function extracts the selected model terms from a fitted selection procedure and returns the corresponding reduced model formula.

Usage

new_formula(object, ...)

Arguments

object A fitted model object produced by a selection routine such as step_gamlss2 or select_gamlss2.
Not used yet.

Details

The function is intended for fitted models that store the outcome of an automatic term-selection step in object$selection$formula. It extracts the selected right-hand side terms and restores the original response on the left-hand side.

For multi-parameter distributional models, the returned object is a Formula with one right-hand side part for each distribution parameter. This makes it convenient to inspect the final model or to refit it without repeating the selection step.

Value

A Formula containing the selected model terms.
