compareFit {semTools}R Documentation

Build an object summarizing fit indices across multiple models

Description

This function will create the template to compare fit indices across multiple fitted lavaan objects. The results can be exported to a clipboard or a file later.

Usage

compareFit(..., nested = TRUE)

Arguments

...

fitted lavaan models or list(s) of lavaan objects

nested

logical indicating whether the models in ... are nested. See the net function for an empirical test of nesting.

Value

A FitDiff object that saves model fit comparisons across multiple models. If the output is not assigned as an object, the output is printed in two parts: (1) nested model comparison (if models are nested) and (2) summary of fit indices. In the fit indices summaries, daggers are tagged to the model with the best fit according to each fit index.
