Tutorial: Getting Started with Amos Graphics
The following path diagram shows a model for these data:
This is a simple regression model where one observed variable, SAT, is predicted as a
linear combination of the other two observed variables, Education and Income. As with
nearly all empirical data, the prediction will not be perfect. The variable Other
represents variables other than Education and Income that affect SAT.
Each single-headed arrow represents a regression weight. The number
1 in the
figure specifies that Other must have a weight of 1 in the prediction of SAT. Some such
constraint must be imposed in order to make the model identified, and it is one of the
features of the model that must be communicated to Amos.
