alsi: Aggregated Latent Space Index for Multiple Correspondence Analysis

Tools for stability-validated aggregation in multiple correspondence analysis (MCA). Implements parallel analysis for dimensionality assessment, bootstrap-based subspace stability diagnostics using Procrustes rotation and Tucker's congruence coefficients, and computation of the Aggregated Latent Space Index (ALSI). ALSI is a person-level summary measure derived from validated MCA dimensions that quantifies departure from independence along stable association directions in multivariate categorical data.
