How Do I Select a Subset of Cases (Observations) to Be Included in an Analysis?
Before an analysis begins (i.e., before the data are processed), you can instruct STATISTICA to select only cases (i.e., rows in the spreadsheet) that meet some specific selection criteria. A facility to define and manage case selection conditions can be accessed from the Tools – Selection Conditions – Edit menu (see page 282) or by clicking on the status bar field Sel, which shows the current status of the Case Selection Conditions. Note that when case selection conditions are disabled, this field reads Sel: OFF, when they are enabled, it reads Sel: ON). Note that there are two types of case selection conditions in STATISTICA – permanent (saved with the datafile) and temporary (associated with the current analysis only).
