Example 17
The following program fits the saturated model (Model B). The program is saved as
Ex17-b.vb.
Following the
BeginGroup line, there are six uses of the Mean method, requesting
estimates of means for the six variables. When Amos estimates their means, it will
automatically estimate their variances and covariances as well, as long as the program
does not explicitly constrain the variances and covariances.
