A cоnfusiоn mаtrix like the оne below is effective for meаsuring clаssification performance.  Consider a ranking exercise where predictions are listed from high to low where the highest score is the most likely match and the lowest is least likely to be a match. The goal is to graph the precision (dependent variable) against the fraction of the total amount of relevant instances that were actually retrieved (independent variable).  Which is the best equation for computing the precision.
