How can you have a model that gives a 100% chance of something happening in the future? Yet that's what it says during the last recession. And it falls off a cliff when the actual recession ended in June 2009.
I was alive and trading during that time, and I reckon the business cycle would be quite easy to predict -as in, the model would be in a textbook- if you could be that confident of recession one day and the opposite the next.
