Definition

Use

You use this parameter to specify which procedure should be used by the scoring algorithm. The following procedures are supported:

  • Weighted Score Tables: You can assign a weighting to each model field. Furthermore, you can assign partial scores to each value (in the case of a discrete model field) or value range (in the case of a numeric model field). The score is calculated as the weighted total of the partial scores across all model fields.
  • Linear regression: The system uses training data records with known score values to determine a linear function that approximates the scores of the training data records.
  • Nonlinear regression: The system uses the training data records with known scores to determine a nonlinear function that approximates the scores of the training data records. The function is a multidimensional spline function of the first order.
