"Microbins" are established to be used for automatic data-point-by-data-point sorting of outcomes of a model. These microbins have much finer "resolution" than standard decile bins. The predicted values are mapped to their respective microbins. As an actual outcome is obtained, it is automatically inserted into the microbin associated with its predicted value. By limiting the predicted score values to three decimal places (or rounding them to three decimal places), each predicted value will have a single microbin in which to be placed, rather than bunching a range of predicted values into a decile bin. To establish the decile bins needed to prepare a standard 10-bin lift chart, the first {fraction (1/10th of the actual outcomes are grouped in a first bin, the second {fraction (1/10th of the actual outcomes are grouped in a second bin, etc. In this manner, the actual outcomes are "sorted" on the fly rather than after the fact.
