How to tie factors

To tie factors:

1.	Select two factors by holding down the Ctrl key while you select each factor with the left mouse button.

2.	Select the Tie factors tool.

3.	In the Factor Name text box, change the name to something meaningful.

4.	Review the other factor properties, such as Nominal Values and Settings. If necessary, change them to the desired values.

5.	Select the Tie tab.

6.	Select Scale or Offset for Tie Type.

7.	Enter a scale or offset for each tied factor, then select Apply.

Adams/Insight updates the computed values for the tied factors.

When you create the tie, Adams/Insight sets default values for the tie value, tie settings, and scale values for the tied factors. If the tied factors have the same value, Adams/Insight automatically moves the value and settings to the tie and sets all scales to 1. If the tied factors have the same absolute values, Adams/Insight automatically makes the tie the positive value, and sets all scales to +1/-1. Otherwise, Adams/Insight sets the tie value to 1 and the tied factor scales to the tied factor nominal values.

To untie factors:

1.	Select the tie in the treeview.

2.	Select the Untie factors tool.

3.	Adams/Insight displays an alert asking whether you want to restore the original factor values.

4.	Select Yes or No.

Adams/Insight deletes the tie and moves the tied factors back to the top level of the treeview. If you asked to restore the original factor values, Adams/Insight resets the factor nominal values to their original values (before they were tied). Otherwise, the factors retain the nominal values computed from the tie.
