  1. On the Association dialog box, click INPUT.
  2. Click data selection.
    Association > Input > Data Selection

  3. On this screen, select:
    • Select Input Source — Users may select between different sources of input. By selecting the Input Source Table, the user can select from available databases, tables (or views) and columns in the usual manner. By selecting the Input Source Analysis, however, the user can select directly from the output of another analysis of qualifying type in the current project. Analyses that can be selected from directly include all of the Analytic Data Set (ADS) and Reorganization analyses (except Refresh). In place of Available Databases, the user can select from Available Analyses, while Available Tables then contains a list of all the output tables that will eventually be produced by the selected analysis.
      Since this analysis cannot select from a volatile input table, Available Analyses will contain only those qualifying analyses that create an output table or view.
    • Select Columns From a Single Table
      • Available Databases (or Analyses) — These are the databases (or analyses) available to be processed.
      • Available Tables— These are the tables and views that are available to be processed.
      • Available Columns — These are the columns within the table/view that are available for the Association analysis.
      • Selected Columns — Select columns by highlighting and then either dragging and dropping into the Selected Columns window, or click on the arrow button to move highlighted columns into the Selected Columns window.
        The Selected Columns window is a split window; you can either insert columns as Group, Item, or Sequence columns. Make sure you have the correct portion of the window highlighted.
        • Group Column — The column that specifies the group for the Association analysis. This column specifies observations or transactions that contain items of some kind.
        • Item Column — The column that specifies the items to be analyzed in the Association analysis. The relationship of these items within the group is described by the Association analysis.
        • Sequence Column — The column that specifies the sequence of items in the Association analysis. This column has a time ordering relationship with the item associated with them.
