Description: Implements a robust multivariate control-chart methodology for
    batch-based industrial processes with multiple correlated variables using the
    Dual STATIS (Structuration des Tableaux A Trois Indices de la Statistique) framework.
    A robust compromise covariance matrix is constructed from Phase I batches with the
    Minimum Covariance Determinant (MCD) estimator, and a Hotelling-type T² statistic is
    applied for anomaly detection in Phase II. The package includes functions to simulate
    clean and contaminated batches, to compute both robust and classical Hotelling T²
    control charts, to visualize results via robust biplots, and to launch an interactive
    'shiny' dashboard. An internal dataset (pharma_data) is provided for reproducibility.

    <doi:10.1080/00401706.1999.10485670> for the MCD estimator.
