Description BifactorIndicesCalculator functions References
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
bifactorIndices
and Mplus
output files using
bifactorIndicesMplus
. For users of other software and those
interested, a matrix of standardized factor loadings can also be input to
bifactorIndices
.
Calculation of bifactor indices for exploratory bifactor models can also be accomplished
using bifactorIndices_expl
for exploratory models fit using psych
or using bifactorIndicesMplus_expl
for exploratory models fit using
Mplus
. For ESEM models fit using Mplus
, please use bifactorIndicesMplus_ESEM
