Modeling in VB.NET
Here is a program for performing the analysis of this example:
The
AStructure method constrains the covariance, fixing it at a constant 0. The program
does not refer explicitly to the variances of age and vocabulary. The default behavior
of Amos is to estimate those variances without constraints. Amos treats the variance of
every exogenous variable as a free parameter except for variances that are explicitly
constrained by the program.
