%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. See Lavit, Escoufier, Sabatier and Traissac (1994)
<doi:10.1016/0167-9473(94)90134-1> for the original STATIS methodology,
and Rousseeuw and Van Driessen (1999) <doi:10.1080/00401706.1999.10485670>
for the MCD estimator.
