Find definitions and interpretations for every statistic in the
Confusion matrix.

The Confusion matrix shows how well the tree separates the classes correctly
using these metrics:

True positive rate (TPR) — the
probability that an event case is predicted correctly

False positive rate (FPR) —
the probability that a nonevent case is predicted incorrectly

False negative rate (FNR) —
the probability that an event case is predicted incorrectly

True negative rate (TNR) — the
probability that a nonevent case is predicted correctly

Interpretation

A low value for % Correct is usually due to a deficient fitted model,
which can be caused by several different reasons. If the % Correct is very low,
consider whether class weights may help. Class weights can help provide a more
accurate model when observations from one class weigh more than observations
from a different class. Also you can change the probability when a required for
a case to be classified as the event.
