In melissagwolf/dynamic: DFI Cutoffs for Latent Variable Models

Dynamic fit index (DFI) cutoffs adapted from Hu & Bentler (1999) for measurement misspecification in hierarchical factor models

Description

This function generates DFI cutoffs adapted from Hu & Bentler (1999) for measurement misspecification in hierarchical factor models using, by default, ML estimation. The default argument is a singular argument: a lavaan object from the cfa function. The function can also accommodate manual entry of the model statement and sample size.

The app-based version of this function can be found at dynamicfit.app.

Usage

hier1HB(
  model,
  n = NULL,
  estimator = "ML",
  plot = FALSE,
  manual = FALSE,
  reps = 500
)

## S3 method for class 'hier1HB'
print(x, ...)

Arguments

model	This can either be a lavaan object from the cfa function, OR a model statement written in lavaan model.syntax with standardized loadings.
n	If you entered a lavaan object for model, leave this blank. Otherwise, enter your sample size (numeric).
estimator	Which estimator to use within the simulations (enter in quotes). The default is maximum likelihood.
plot	Displays distributions of fit indices for each level of misspecification.
manual	If you entered a lavaan object, keep this set to FALSE. If you manually entered standardized loadings and sample size, set this to TRUE.
reps	The number of replications used in your simulation. This is set to 500 by default in both the R package and the corresponding Shiny App.
x	hier1HB object
...	other print parameters

Value

Dynamic fit index (DFI) cutoffs for SRMR, RMSEA, and CFI.
