bifactory: (Bifactor) ESEM with Continuous (MLR) or Ordered (WLSMV) Data
Fits bifactor exploratory structural equation models (B-ESEM),
together with standard exploratory structural equation modeling (ESEM)
and confirmatory factor analysis (CFA), for continuous and
ordered-categorical data. Continuous models use 'lavaan' native efa()
blocks with robust maximum likelihood (MLR) estimation.
Ordered-categorical ESEM defaults to the 'lavaan' weighted least squares
mean- and variance-adjusted (WLSMV) estimator; ordered B-ESEM uses a
custom diagonally weighted least squares (DWLS) path with polychoric
correlations from 'psych', rotation-delta standard errors via 'numDeriv',
and a mean- and variance-adjusted chi-square. Target, geomin, and oblimin
rotations use 'GPArotation'; the bifactor ESEM approach follows Morin,
Arens and Marsh (2016) <doi:10.1080/10705511.2014.961800>. Additional
features include multi-group measurement invariance (configural through
strict, with partial invariance), ESEM-within-CFA conversion, McDonald's
omega reliability suite, and the Mehrvarz and Rouder (2026)
<doi:10.31234/osf.io/95enc_v3> alignment ratio check for independent
cluster model confirmatory factor analysis (ICM-CFA) misspecification.
An optional 'MplusAutomation' interface allows side-by-side comparison
with 'Mplus' output.
