Description: Implements Factor Analytic Profile Analysis of Ipsatized
        Data ('FAPA'), a metric inferential framework for pattern
        detection and person-level reconstruction in multivariate
        profile data.  After row-centering (ipsatization) to remove
        profile elevation, 'FAPA' applies singular value decomposition
        ('SVD') to recover shared core profiles and individual pattern
        weights.  Dimensionality is determined by a variance-matched
        Horn's parallel analysis.  A three-stage bootstrap verification
        framework assesses (1) dimensionality via parallel analysis,
        (2) subspace stability via Procrustes principal angles, and (3)
        profile replicability via Tucker's congruence coefficients. BCa
        bootstrap confidence intervals for core-profile coordinates are
        computed via the canonical 'boot' package implementation of
        Davison and Hinkley (1997) <doi:10.1017/CBO9780511802843>.
