Categories Column
The categories column contains a list of the indexes of the selected elements, in the form {3,5}. For single response variables, the categories column should never contain more than one index. If the respondent did not select any categories, the column is {}. In UNICOM Intelligence Data Model 2, the element index is the element value assigned by the Metadata Model.
Elements that are included in the categories columns
n01
A normal category element.
n15
A normal element that is not meant for printing in a table. In Basic mode, a tabulator aggregates and prints it. The "don't print" instruction is available to tabulators operating in Quanvert-aware mode.
rej=1
An element that collects the cases that are included in the variable, but excluded from its rej=0 base element(s) and all category elements.
Note There are a number of element options (nontot, noexport, ex=, inc=;median, and inc=;percentile) that can be applied to these elements and that result in the element being put into the extra column. Sometimes these element options are applied automatically by the Quantum compiler.
