and see how the original responders distribute in the 10 decile. If regularities are found, we will see more responders in the top decile than bottom decile (Hughes, 1996). Table 2 is an example of the lift table. In this example, the testing set has a total of 100,000 examples (thus each decile has 10,000), with a total of 1,000 positive examples. Clearly, this lift table shows a distribution in which more responders are gathered in the top deciles than bottom deciles.
