You can define predictor values to calculate customer score. By using factors
such as age and income, you can, for example, assess credit risk.
Use the
Scorecard tab to define the predictors by adding properties, by
determining how the score should be calculated, and by assigning the weight of each
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).
-
In Dev Studio, click .
-
In the Scorecard tab, double-click a scorecard instance.
-
To combine the score, in the scorecard instance tab, in the Combiner
function field, choose one of the following options:
- To combine the total sum of score values between predictors, click
Sum.
- To combine the score for each predictor and take the lowest value, click
Min.
- To combine the score for each predictor and take the highest value, click
Max.
- To combine the total sum of score values between predictors divided by the number
of predictors, click Average.
-
In the Predictor expression field, define predictors in one of
the following ways:
-
In the Condition field, define the criteria to match the
predictor values to the score.
For example: If the .Score property is Less Than or
Equal to 20, the score is
0.2.
-
In the Score field, enter the score for cases that fall into the
defined condition.
For example: You can define the score in one of the following ways:
- Optional:
In the Otherwise field, enter a default score for cases that do
not match the defined conditions.
-
In the Weight field, define the coefficient of the
predictor.
