The Cumulative Lift Table is produced for deciles based on the probability values. Note that the deciles are labeled such that 1 is the highest decile and 10 is the lowest, based on the probability values calculated by logistic regression. Within each decile, the following measures are given:
- count of “response” values
- count of observations
- percentage response (percentage of response values within the decile)
- captured response (percentage of responses over all response values)
- lift value (percentage response / expected response, where the expected response is the percentage of responses over all observations)
- cumulative versions of each of the measures above
The following is an example of a logistic regression Cumulative Lift Table.
