A robust compromise\ncovariance matrix is constructed from Phase I batches with the\nMinimum Covariance Determinant (MCD) estimator, and a\nHotelling-type T² statistic is applied for anomaly detection in\nPhase II. The package includes functions to simulate clean and\ncontaminated batches, to compute both robust and classical\nHotelling T² control charts, to visualize results via robust\nbiplots, and to launch an interactive 'shiny' dashboard. An\ninternal dataset (pharma_data) is provided for reproducibility.\nSee Lavit, Escoufier, Sabatier and Traissac (1994)\n for the original STATIS\nmethodology, and Rousseeuw and Van Driessen (1999)\n for the MCD estimator.", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "LazyData": "true", "Roxygen": "list(markdown = TRUE)", "RoxygenNote": "7.3.2", "URL":
