Exercise

Compare Two Models

In the last exercises, you created two models of the epi, and these models have been loaded for you.

The original model epi.model and the updated model with the modified path epi.model1 can now be compared using the anova() function to determine if the change in fit indices was a large change. We can use the anova() function because these models are nested, which means they are the same manifest variables with different parameters.
