Bifactor Indices Calculator

The calculator computes bifactor indices such as explained common variance (ECV), hierarchical Omega (OmegaH), percentage of uncontaminated correlations (PUC), item explained common variance (I-ECV), and more. This package is an R version of the 'Excel' based 'Bifactor Indices Calculator' (Dueber, 2017) with added convenience features for directly utilizing output from several programs that can fit confirmatory factor analysis or item response models.
