On multiple-class prediction of issuer credit ratings
industry effect issuer credit rating market-driven variable optimal cutoff value ordered probit model selection bias
2011/8/26
For multiple-class prediction, a frequently used approach is based on ordered probit model. We show that this approach is not optimal in the sense that it is not designed to minimize the error rate of...
