In bifactory: (Bifactor) ESEM with Continuous (MLR) or Ordinal (WLSMV) Data

Generate, Run, and Compare B-ESEM Invariance Models Against Mplus

Description

Creates complete Mplus .inp files for every level fitted in inv (configural, weak, strong, strict and, when esem_invariance() was run with through, latent var/cov and latent means), runs them via MplusAutomation, then prints a side-by-side comparison of fit statistics against the R results from esem_invariance.

Usage

run_mplus_besem_invariance(
  inv,
  output_folder,
  mplus_command = "mplus",
  group_labels = NULL,
  missing_code = -999,
  difftest = TRUE
)

Arguments

inv	An esem_invariance object (from model = "besem").
output_folder	Character. Folder where data.dat, .inp, and .out files will be written. Created if it does not exist.
mplus_command	Character. Full path to the Mplus executable. Default "mplus" (works if Mplus is on the system PATH).
group_labels	Named character vector mapping group values to Mplus labels, e.g. c("1" = "MALE", "2" = "FEMALE"). If NULL (default) labels are auto-derived as G1, G2, ...
missing_code	Numeric. Missing value sentinel written to the data file. Default -999.
difftest	Logical. Generate DIFFTEST constraint files for chained nested-model comparisons (strong vs weak, strict vs strong). Default TRUE.

Value

A data frame (invisibly) with _R, _Mplus, and delta_ columns for each fit statistic. Printed as a table.

Examples

## Not run: 
# Requires a licensed Mplus installation reachable via `mplus_command`.
inv <- esem_invariance(spec, model = "besem")
cmp <- run_mplus_besem_invariance(
  inv,
  output_folder = tempfile("mplus_inv_"),
  mplus_command = "C:/Program Files/Mplus/mplus.exe",
  group_labels  = c("1" = "MALE", "2" = "FEMALE")
)

## End(Not run)
