For example, one group could be the probability of default given that the acid ratio is between the 40th and 60th percentile of firms, the turnover is between the 80th and 100th percentile and the prior quarter's change in GDP was between the 40th and 60th percentile. The best solution that I have found is to create Pearson-Tukey groups and to calculate the binomial over each group. In addition, because of the high level of correlation by design in financial statements, the assumptions of logistic regression are strongly violated. They do not generate probability distributions that can safely be gambled with. Bayesian methods are coherent.Ĭoherence is the statistical property by which fair gambles can be placed. The best solution is a Bayesian solution because you are gambling money. The extreme scores are predictive, but a load of empirical research shows the intermediate values are not predictive. The system computes results for all methods and all loan pools, allowing the bank to optimize its CECL configuration and avoid the worst impacts of the new standard.Yes, you can.
