%description
Implements Goldberg's (2006) <doi:10.1016/j.jrp.2006.01.001> bass-ackwards
method and modern descendants for hierarchical structural analysis.
Extracts solutions from 1 to k factors using principal component analysis
(PCA), exploratory factor analysis (EFA), or exploratory structural
equation modeling (ESEM) engines. It then describes the hierarchy through
the correlations between the factor scores of different levels. It
computes them with linear algebra from the scoring weights and the
correlation matrix the fit uses, so they are exact for that matrix. Waller
(2007) <doi:10.1016/j.jrp.2006.08.005> showed, for principal components,
that these correlations follow from the correlation matrix alone. Includes
the Forbes (2023) <doi:10.1037/met0000546> extension for redundancy
pruning and all-levels cross-correlations.
