Arcgis Python Frequency Of Column Values

The values can be separated using the concatenation_separator parameter. MODE The mode the most common value for the specified field will be identified. If more than one value is equally common, the lowest value will be returned. DBMS_SUM The values for the specified field will be added together.

The output table will contain the frequency for each unique combination of the specified frequency fields. If a summary field is specified, the unique attribute values of the frequency calculation are summarized by the numeric attribute values of each summary field. When using layers, only the currently selected features are used in calculations.
