In jgendrinal/creditscore: Tidy workflows for credit scoring

Description

scale_double_odds takes a scorecard model and formats the output using points-to-double and the set score representing odds of default at 50-to-1. Both are input by the user.

Usage

scale_double_odds(score_model, odds_fifty = 600, pdo = 20)

Arguments

score_model	A modified model object containing the model and associated WOEs
odds_fifty	A numeric, the point score of a borrower with a probability of default of 50 to 1, default input is 600 points
pdo	A numeric, score points given doubling odds of a default, defaults to 20 points

Details

This is useful for representing the credit scores in the three-digit format common in credit scoring companies like Equifax, FICO, and TransUnion. Scaling is performed not to improve model predictability, but to improve readability by stakeholders. This will generally depend on where the credit scores are being used.

Value

A modified model object containg the offset and factor computed by the function
