What is meant by the term “lift”? The term “lift” describes the improved performance of an exact or specific amount of effort on a modeled sampling, as opposed to a random sampling (Spang, 2010). In other words, if you are able to market via a model to say, a given number of random customers (e.g. 1000), and we expect that 50 of them would be successful, then a model that can generate 75 successes would have a 50 percent lift. “Lift” is possibly the most commonly metric used to measure targeting model performance in marketing applications – the purpose of which, is to identify a subgroup or target from a larger population (Coppock, 2002 and Spang, 2010). The subgroup targeted or target members selected are those who are most likely to respond positively to a marketing offer. As such, the model is doing well if as predicted – the response within the targeted section is much better than average when compared to the population as a whole. Lift then, is simply the ratio of these values: target response divided by average response (Coppock, 2002). “Lift Charts” and “Lift Curves” are terms often seen in direct marketing. To quickly define them here – a lift curve is a popular technique which assigns a “probability of responding” score when used in an attempt to determine who the likely responders from a population are.
“The lift curve helps us determine how effectively we can “skim the cream" by selecting a relatively small number of cases and getting a relatively large portion of the responders” (Keating, 2013).
A lift chart or a “Gains Chart” is a convenient summary of all the cumulative lift curves whereby all the information in these multiple classification matrices are turned into a graph (Keating, 2013 and Coppock, 2002).
