How Do I Merge Two STATISTICA Datafiles?
Select Merge from the Data menu to display a submenu of merge options. Either cases (rows of data) or variables (columns of data) can be merged. In other words, either the second file is appended to the “bottom” of the first one, or it is appended to the “right side” of the first one. If you select Merge – Variables & then additional options are available. For example, you can select Relational or Relational hierarchical option buttons, for which a key variable (in each file) is used to “match” cases based on the corresponding values of the key.
