FitDiff-class: Class For Representing A Template of Model Fit Comparisons

In semTools: Useful Tools for Structural Equation Modeling

Description

This class contains model fit measures and model fit comparisons among multiple models

Usage

## S4 method for signature 'FitDiff'
show(object)

## S4 method for signature 'FitDiff'
summary(object, fit.measures = "default", nd = 3)

Arguments

object	object of class FitDiff
fit.measures	character vector naming fit indices the user can request from fitMeasures. If "default", the fit measures will be c("chisq", "df", "pvalue", "cfi", "tli", "rmsea", "srmr", "aic", "bic"). If "all", all available fit measures will be returned.
nd	number of digits printed

Slots

name

character. The name of each model

model.class

character. One class to which each model belongs

nested

data.frame. Model fit comparisons between adjacently nested models that are ordered by their degrees of freedom (df)

fit

data.frame. Fit measures of all models specified in the name slot, ordered by their df

Objects from the Class

Objects can be created via the compareFit function.
