To use subsetting in an MGPS data mining, you must select a subset variable.
1. On the Select Variables page, select Item and, optionally, select Stratification variables.
2. Check Define subsets.
3. Click Next.
The Select Subset Variable page appears. If you also checked Define custom terms on the Select Variables page, the Select Subset Variable page appears after you add custom terms.
4. From the Subset variable list, select the variable to use for subsetting.
You can select only one subset variable, and you cannot select the same variable to be both an item variable and a subset variable in the same data mining run.
5. Click Next.
The Define Subset Values page appears.
6. Continue with Defining subset values.
