Researchers have explored various multivariate outlier detection methods for district heating system data, aiming to identify operational irregularities and reduce gas consumption and CO2 emissions. The study evaluated techniques including Z-score, Mahalanobis distances, Principal Component Analysis (PCA), Isolation Forest, and Hotelling's T-squared test. An ensemble method, combining PCA, Isolation Forest, and the Hotelling method, was adopted as the final approach after expert consultation confirmed their relevance. AI
