Stat-Xplore : Zero Suppression

Stat-Xplore's zero suppression options are designed to help you reduce noise in your tables so you can concentrate on what's important. When you activate zero suppression, Stat-Xplore will automatically remove rows and columns that contain only zeros.

This can be particularly useful for very large tables with small values, as it can reduce the size of the table significantly, making it easier to focus on the results.

For example, without zero suppression this table has 2 columns and 714 rows:

With automatic zero suppression enabled, Stat-Xplore automatically removes all the rows and columns that have only zeros in them. This reduces the number of rows down to just 57 (the row count remains the same even though row suppression is enabled because this table does not have any rows that only have zero values):

To activate or deactivate zero suppression, select the Rows and Columns options from the Table Options menu at the top of the table. You can choose to apply suppression to rows, columns, or both.

If you are using wafers, then Stat-Xplore determines whether to suppress a row or column by looking at the entire cube, not just the currently visible wafer. A row or column will only be suppressed if it contains only zeros on all of the wafers.

This means that you may still see rows and columns with all zero values in your table: if a row or column only contains zeros on the current wafer, but has values on at least one of the other wafers, then it will not be suppressed.
