Construction of related indicators
Percentage of cumulative early warning bad guys in the interval = cumulative warning bad people / cumulative warning bad people
Proportion of accumulative bad actors = accumulative proportion of bad customers

in principle:
1. The principle of killing good people by mistake and not letting bad people go. Choose a score interval with a high recall rate
2. Don't kill good people by mistake, and tolerate the principle of letting go of some bad people. Just choose the score interval with high precision
Tips: The above scores are divided into 10 equidistant boxes. If you want to be more detailed, you can divide them by 20 and 30 equidistant boxes.
