In order to increase the lift (result) of a rule, you can add more variables to the rule. Each time we add, remove or change the ranges of a variable in the rule, a new hyperlift calculation is launched adapting to the new situation. You need to click on "Recompute" to launch the new calculation.
The variables in the field “Add variable to the rule” are ranked by hyperlift in function of the variables and ranges that are already inside the rule. The bigger the green bar, the stronger the variable's impact.
You can choose the variable that best fits your rule and it will choose automatically the best range in interaction with the 2 already existing parameters and will obtain an increase of the lift.
You have to click on "Save" to keep the modification.
