Automatic (numeric) Variables are always initialized to zero. Skipped Data Element variables are initialized as specified on the Data Element If Skipped and Calculations tabs. The default setting treats a skipped variable as Not Applicable and uses the value of zero for Not Applicable in a calculation. All numeric variables within QDS have a numeric range, a separate numeric code (e.g., 97 for Don’t Know), and a string representation (e.g., Don’t Know). When the Warehouse Manager exports data to SPSS or SAS, it provides a number of options for dealing with special values like Don’t Know or Not Applicable.
