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.
