WebOct 17, 2011 · Lift is nothing but the ratio of Confidence to Expected Confidence. In the area of association rules - "A lift ratio larger than 1.0 implies that the relationship between the antecedent and the consequent is more significant than would be expected if the two sets were independent. The larger the lift ratio, the more significant the association." WebLift is the ratio of the gain percentage relative to the expected random result. The dotted reference line represents a cumulative lift of 1, which means that there is no gain compared with random. In this example, the lift chart shows an increase above the reference line that gradually drops off.
