**TLDR:** A statistical approach that performs anomaly detection through covariance estimation that is more robust to outliers.

<p>Robust covariance methods provide more reliable estimates of center and spread when classical covariance estimation is distorted by outliers. Anomaly detection can then be performed using Mahalanobis-like distance measures. These methods can be useful especially in multivariate and medium-scale datasets. However, distributional form and feature scaling still remain important considerations.</p>
