areamajority

areamajority

Most often occurring cell value within an area

Result = areamajority(expression, areaclass)

areaclass

spatial boolean, nominal, ordinal

expression

spatial boolean, nominal, ordinal

Result

spatial type of expression

Operation

areaclass Identifies the class to which a cell belongs: cells with corresponding values on areaclass are member of a separate class. For each separate class the most often occurring cell value on expression is determined. This value is assigned to all cells belonging to that class. This is done for all classes and saved as Result. If two values both occur the same number of times, the largest value of these values is assigned.

Notes

A cell on areaclass with missing value will result in a missing value on Result at the corresponding cell.
