The BifactorIndicesCalculator package provides functions use to compute indices described in Rodriguez et al. (2016) for confirmatory or exploratory models.
The BifactorIndicesCalculator package includes helper functions that can compute the various
indices from Rodriguez et al. (2016) for fitted lavaan or mirt objects using
Mplus output files using
bifactorIndicesMplus. For users of other software and those
interested, a matrix of standardized factor loadings can also be input to
Calculation of bifactor indices for exploratory bifactor models can also be accomplished
bifactorIndices_expl for exploratory models fit using psych
bifactorIndicesMplus_expl for exploratory models fit using
Mplus. For ESEM models fit using
Mplus, please use
