Selecting the right objective measure for association analysis

data mining.1 The table also shows that different measures can lead to substantially different rank-ings of contingency tables. For example, E10 is ranked highest according to the I measure but lowest according to the f-coefficient; while E3is ranked lowest by the AV measure but highest by the IS measure. Thus, selecting the right measure
