IBM® SPSS® Amos™ 28
In Amos Graphics:
1.Double-click the object whose parameters you want to constrain. (The Object Properties dialog opens.)
2.Select Parameters. (The dialog contains a box for each parameter associated with the object. For example, if you double-clicked an exogenous variable, there is a box labeled Variance. If means are explicit model parameters, there is also a box labeled Mean.)
3.Name each parameter or assign it a value by typing a string in its box.
In an Amos program, use the AStructure, Path, Cov, Var, Mean or Intercept method of the AmosEngine class.
Tip
If the Object Properties dialog is already open, you only need to click once on an object to change the constraints on its parameters.
