Comparisons of linear regression and survival analysis using single and mixture distributions approaches in modelling LGD

Estimating Recovery Rate and Recovery Amount has become important in consumer credit because of the new Basel Accord regulation and because of the increase in number of defaulters due to the recession. We compare linear regression and survival analysis models for modelling Recovery rates and Recovery amounts, so as to predict Loss Given Default (LGD) for unsecured consumer loans or credit cards. We also look at the advantages and disadvantages of using single distribution models or mixture distribution models for estimating these quantities.
