FitDiff-class: 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 FitDiff
show(object)
# S4 method for 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

Run this code

# NOT RUN {
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"))

# }
# NOT RUN {
## Save results to a file
saveFile(modelDiff, file = "modelDiff.txt")

## Copy to a clipboard
clipboard(modelDiff)
