Four years of research led to a specific decision tree data mining algorithm yielding best results. Results obtained from the BC database were excellent, revealing $4.7 billion ...

The data mining decision tree algorithm selected for this research resulted from testing several dozen different data mining techniques, methodologies, and software over a 4-year period.

Trees generally have a harder time coming up with calibrated probabilities. This can be helped somewhat with bagging and Laplace correction. Trees tend to have problems when the base rate is very low.
