WebJun 8, 2024 · Steps to calculate lift is as follows: Calculate the probability of each of the observations. Sort the data based on the predicted probability in descending order. Group the data based on population. Typically they are grouped into deciles i.e. into 10 groups. Get the max and min probability of each of the deciles. 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 lift at 10% for the category Yes is 30%/10% = 3.0. It provides another way of looking at the information in the cumulative gains chart.
