Example 26
Performing Bayesian Estimation Using Amos Graphics
To illustrate Bayesian estimation using Amos Graphics, we revisit Example 3, which
shows how to test the null hypothesis that the covariance between two variables is 0 by
fixing the value of the covariance between age and vocabulary to 0.
Estimating the Covariance
The first thing we need to do for the present example is to remove the zero constraint
on the covariance so that the covariance can be estimated.
E Open Ex03.amw. If you performed a typical installation, the path will be
C:\Program Files\IBM\SPSS\Amos\21\Examples\<language>.
E Right-click the double-headed arrow in the path diagram and choose Object Properties
from the pop-up menu.
E In the Object Properties dialog box, click the Parameters tab.
E Delete the 0 in the Covariance text box.
E Close the Object Properties dialog box.
