I read some definitions of recall and precision machine learning, data analysis recall and precision in classification. Precision can be thought of as a measure of a classifiers exactness a low precision can also indicate a large number of false positives the precision of the all no recurrence model is 0/(0+0) or not a number, or 0 the precision of the all recurrence model is 85/(85+201) or 030 the precision of the cart model is 10/(10+13) or 043.
