Associated Database Icon

• The Associated Data Set icon is perhaps the most common symbol appearing in the Status Bar.
• It appears whenever data is associated with a network.
• Beyond displaying the icon itself in the Status Bar, additional information can be displayed on top of the icon.
  • A question mark icon indicates that there are missing values in the associated data.
  • The weight icon indicates that the associated data contains a weight variable assigning weights to rows/cases.
  • The presence of a “T” icon means that the data set is split into a learning and test set.
  • The stratification icon indicates that the data was stratified.
  • If all tags were displayed simultaneously, the database icon would look like this:
