Data suppression – Other
Suppression of data may be applied for product-specific reasons due, typically, to the size of the product and/or the constraints of the media on which the product is being disseminated.
Incidence reporting is a process used to order or rank characteristic data by size within products. It can be used as a method to select only the 'n' highest categories of a characteristic for inclusion in a product.
Zero suppress refers to the removal of records in which all of the counts are equal to zero. This method is used to reduce the size of an output product by removing any rows of the output matrix where all data are equal to zero.
