In an in-depth Q&A, Professor Edward Altman discusses how financial markets have changed in the 50 years since he developed his Z-score model of predicting bankruptcy
— November 9, 2018
Excerpt from Bloomberg -- "Since then, the accuracies have been somewhere between 80 percent and 90 percent based on one year before bankruptcy. The accuracy is not as high as when we first built the model, but it’s still being used. There are other variables that one could use, and it probably makes sense to build new models using new tools such as machine learning."
