Scorecard rule form  Completing the Scorecard tab
Use this tab to define the predictors by adding properties, defining how the score should be calculated, and assigning the weight of each predictor.
Field  Description 

Combiner Function 
Choose the method used to combine the score.

Predictor Expression 
Select existing single value properties. You can also define predictors using an expression (for example,
@if(.EmploymentStatus=="Employed",.Salary,.CreditAmount
).
Note: By default, every predictor is assigned the same weight (1). Changing the default value results in calculating the final score as weight multiplied by score (for example, 0.5*30). Maintaining the default value implies that, effectively, only score is considered because the coefficient is 1 (for example, 1*30).

Condition  Define the criteria to match the predictor values to the score. 
Score 
Enter the score for cases falling into the defined condition. The score can be defined explicitly (20), through a property (.Score) or involve a computation expressed by an expression (
.Score*.PenaltyMargin
or
@divide(.Score,100)
).

Otherwise  Optional: Enter a default score for cases that do not match the defined conditions. 
Weight  Define the coefficient of the predictor. By default, every predictor is assigned the same weight (1). Changing this value results in the calculation of the final score as weight multiplied by score (for example, 0.5*30). Maintaining the default value implies that only the score is considered because the coefficient is 1 (for example, 1*30).
