Details and restrictions of the column proportions test
The column proportions test is not suitable for all tables. When you request the test on a table that is structurally unsuitable, UNICOM Intelligence Professional changes the specified table level (a warning message is not provided). It is up to you to make sure that the data in the table is generally suitable for testing, that the sample size is suitable, etc.
UNICOM Intelligence Reporter displays a message if you define a column proportions test on an unsuitable table or if you change a table that has a column proportions test defined so that it is no longer suitable for the test. When this happens, you can either adjust the table so that it conforms to the restrictions described here, or you can remove the test from the table. However, sometimes UNICOM Intelligence Reporter - Survey Tabulation UNICOM Intelligence Reporter is unable to determine that a table or a section of a table is unsuitable for the test until it actually attempts to perform it--for example, when a table has only two category columns and all of the values in one of those columns are zero. When this happens, UNICOM Intelligence Reporter - Survey Tabulation UNICOM Intelligence Reporter simply skips the test.
