Class For Representing A Template of Model Fit Comparisons

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")

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.

Slots

name: The name of each model
nested: Model fit comparisons between adjacent nested models that are ordered based on their degrees of freedom (df)
ordernested: The order of nested models regarding to their df
fit: Fit measures of all models specified in the name slot

Objects from the Class

Objects can be created via the compareFit function.

Examples


HW.model <- ' visual =~ x1 + x2 + x3
              textual =~ x4 + x5 + x6
              speed =~ x7 + x8 + x9 '

out <- measurementInvariance(model = HW.model, data = HolzingerSwineford1939,
                             group = "school", quiet = TRUE)
modelDiff <- compareFit(out)
summary(modelDiff)
summary(modelDiff, fit.measures = "all")
summary(modelDiff, fit.measures = c("aic", "bic"))
