add_tariff_segments: Add derived tariff segments to portfolio data

In insurancerating: Actuarial Tools for Insurance Pricing Models

Add derived tariff segments to portfolio data

Description

Adds the tariff segments derived by derive_tariff_segments() as a new factor column to a portfolio data set. This is the recommended way to attach derived tariff segments to the same portfolio rows that were used to fit the risk factor GAM.

Usage

add_tariff_segments(data, segments, name = NULL, overwrite = FALSE)

Arguments

data	A data frame to which the tariff segments should be added.
segments	Object of class "tariff_segments", produced by derive_tariff_segments(). Old "tariff_classes" objects are accepted for backward compatibility.
name	Character string. Name of the new output column. If NULL, the name is based on the risk factor name, for example "age_policyholder_segment".
overwrite	Logical. If FALSE, the function stops when name already exists in data.

Value

A data frame with the derived tariff segment column added.
