The black line is not the baseline, but the cumulative capture rate. The capture rate is the proportion of all the events that fall into the group/bin. E.g. if 90 out of total 100 positive outcomes/events fall into the first bin, then the capture rate for that bin is 0.9. The green line is the cumulative lift curve, so by definition ...

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. WebThe lift chart is derived from the cumulative gains chart; the values on the y axis correspond to the ratio of the cumulative gain for each curve to the baseline. Thus, the …

WebSep 12, 2024 · In the Cumulative Lift chart, the Y-axis shows the coefficient of improvement over a random model. For example, if you pick 10% of rows randomly, you expect to catch 10% of the class you're interested in. If the model's top 10% of predictions catch 28% of the selected class, the lift is indicated as 28/10 or 2.8. WebDETAILS: The plots produced by the GainLift macro are commonly used to assess the predictive ability of a binary response model, such as a logistic or probit model or of a decision tree. Gains and lift plots are popular in direct marketing and credit scoring fields. Another plot, the ROC plot, also summarizes predictive ability.
