fit_ewc: Fit an ESEM-within-CFA Model

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

Fit an ESEM-within-CFA Model

Description

Generates EWC lavaan syntax from a fitted ESEM solution and estimates it as a standard lavaan::cfa() model – no rotation required.

Usage

fit_ewc(
  esem_fit,
  spec,
  referents = NULL,
  var_fixed = TRUE,
  missing = NULL,
  custom_syntax = NULL,
  ...
)

Arguments

esem_fit	An esem_fit object (results$fit_esem).
spec	An esem_spec from specify_model.
referents	Named character vector of referent items or NULL (auto-selected). See find_ewc_referents.
var_fixed	Logical. Identification mode. Default TRUE (factor variances = 1). See ewc_syntax for details.
missing	Character. Missing data handling. Defaults to "pairwise" for ordered, "listwise" for continuous.
custom_syntax	Character or NULL. Supply a hand-edited syntax string (from ewc_syntax) instead of auto-generating. When non-NULL, referents and var_fixed still control the lavaan::cfa() options (std.lv).
...	Additional arguments forwarded to lavaan::cfa().

Value

An object of class "ewc_fit":

lavaan_fit

lavaan fit object; all lavaan generics work on it.

syntax

lavaan model string used.

referents

Named vector of referent items.

var_fixed

Identification mode used.

estimator

Estimator ("MLR" for continuous, "DWLS" for ordered).

spec

The spec object.
