080529: Some criteria scores are null and won't be used in final score calculation. The affected records have final score values of Null. Affected records (only includes first 30): <value> = <value>.

Description

Some of the records in the dataset have null values for criteria scores. In suitability analysis, the first 30 null values encountered are listed. The null values are caused by a combination of negative criteria values and specific scoring parameter values.

Solution

If the criteria contain negative values and Raw is specified as the Method to Scale Input Criterion Values parameter value, do not specify Product or Geometric Mean for the Method to Combine Scaled Criteria parameter value. Using the default scoring parameter values will ensure that null scoring values are not returned in this scenario.
