Exposure at Default Models

Estimate exposure at default

Calculate the Exposure at Default (EAD) using a Regression, Tobit, or Beta model to predict the amount of loss exposure for a bank when a debtor defaults on a loan. Calculate the estimated loss reserves using Expected Credit Loss (ECL) calculator.
