| + | The value mapped to the key by each key/value pair is used as the number of key occurrences for the calculation of the //Statistical Key Attributes//. Keys associated with negative or zero values are supposed not be presented in the table when the key attributes are being calculated and the corresponding keys are ignored. | ||
| + | If you do not want the value associated with the key to the used as the number of key occurrences, use a [[Calculate Lookup Table]] to turn the associated values into ones and run the attribute calculation on the resulting table -- the expression ''1'' can be used for that purpose. | ||
