Computing the Significance Value of the Test Statistic

  1. To compute the significance value for the likelihood ratio test, from the menus choose:

    Transform > Compute Variable...

  2. In the Compute Variable dialog, type pvallrt as the Target Variable.
  3. Type sig.chisq(0.002,1) as the Numeric Expression.
  4. Click OK.

The significance value of the test is saved to the variable pvallrt, and its value is 0.96. Since the significance value is greater than 0.10, you can safely accept the null hypothesis that the compound symmetry covariance model fits as well as the unstructured covariance model.
