In jasonmoy28/psycModel: Integrated Toolkit for Psychological Analysis and Modeling in R

Comparison of Model Fit

Description

Compare the fit indices of models (see below for model support)

Usage

compare_fit(
  ...,
  digits = 3,
  quite = FALSE,
  streamline = FALSE,
  return_result = FALSE
)

Arguments

...	model. If it is a lavaan object, it will try to compute the measurement invariance. Other model types will be passed to performance::compare_performance().
digits	number of digits to round to
quite	suppress printing output
streamline	print streamlined output
return_result	If it is set to TRUE, it will return the the compare fit data frame.

Value

a dataframe with fit indices and change in fit indices

Examples

# lme model

fit1 <- lm_model(
  data = popular,
  response_variable = popular,
  predictor_var = c(sex, extrav)
)

fit2 <- lm_model(
  data = popular,
  response_variable = popular,
  predictor_var = c(sex, extrav),
  two_way_interaction_factor = c(sex, extrav)
)

compare_fit(fit1, fit2)

# see ?measurement_invariance for measurement invariance example
