Add coefficient restrictions to a refinement workflow

Adds a restriction step to a rating_refinement object.

restrict_coef() is deprecated as of version 0.9.0. Please use the refinement workflow instead:

prepare_refinement(model) |>
  add_restriction(...) |>
  refit()

Usage

add_restriction(model, restrictions)

restrict_coef(model, restrictions)

Arguments

model

Object of class rating_refinement, usually created with prepare_refinement().

restrictions

data.frame with exactly two columns: the original risk factor level and the replacement relativity to use in the refined tariff.

Value

Object of class rating_refinement.

Details

add_restriction() is part of the new refinement workflow and is intended to be used in combination with prepare_refinement() and refit().

The legacy function restrict_coef() remains the only function that should be applied directly to a model object.
