The following illustration shows how the Manage Models dialog is used to specify Model B of Example 11. The list of parameters at the left of the dialog shows that some regression weights are named. The names are b1, b2, b3, b4, b5, b6, g1, g2, g3, g4, g5, g6. Also, at least one regression weight is fixed at the value, 1. No other parameters (covariances, variances, means or intercepts) are named or assigned values. The Parameter Constraints box shows that regression weights named g1 are required to be equal to regression weights named b1, regression weights named g2 are required to be equal to regression weights named b2, and so on.

Here are some more examples of equality constraints that you can enter in the Parameter Constraints box:

      a = b = c = d
      a = 5
      a = b = c = d = 5
