We develop Bayesian inference for the model using Markov chain Monte Carlo methods. Implementation of the model is illustrated using actual default/prepayment data and additional insights that can be obtained from the Bayesian analysis are discussed.","authors_text":"Arnab Bhattacharya, Refik Soyer, Simon P.
