Examine Modification Indices
The fit indices for our epi.model
are low (in the .70s) for CFI and TLI. You can use modification indices to find potential parameters (paths) to add to the model specification to improve model fit.
Examine the modification indices for the epi.model
and add the path with the largest mi
to your model. The libraries and model have been loaded for you. After you edit your model, rerun the model summary to examine the change in fit indices.
