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>.
