IBM® SPSS® Amos™ 28

Displays a "best fit" graph. Each point in the graph represents a model that fits as well as or better than any other model that has the same number of parameters.

In the following example, the best 16-parameter model has C = 67.342. The best 17-parameter model has C = 3.071. And so on.

Note that the best model for a fixed number of parameters does not depend on the choice of fit measure.

Clicking different fit measures under the Fit measures heading changes the vertical axis of the best fit graph and changes the shape of the configuration of points. However the points in the best fit graph always represent the same set of models regardless of the choice of fit measure.
