By-variables

A separate analysis will be performed for each by-group. The by-variable information is automatically loaded when you open the SEER*Stat Export dictionary associated with your data file. If you created your data file with software other than SEER*Stat, you must manually add by-variables. To add a by-variable, click the "Add..." button, select the desired variable, and click OK. Select the "Exclude..." button if you want to remove cohorts from the next processing.
