  "Description": "Outlier detection using leave-one-out kernel density\nestimates and extreme value theory. The bandwidth for the\nkernel density estimates is computed from the edge lengths of\nthe Euclidean minimum spanning tree of the data. Using the\npeak-over-threshold method, a generalized Pareto distribution\nis fitted to the negative log of the leave-one-out kernel\ndensity estimates to identify outliers. See Kandanaarachchi and\nHyndman (2022) <doi:10.1080/10618600.2021.2000425> and Hyndman,\nKandanaarachchi and Turner (2026)\n<doi:10.48550/arXiv.2603.22636>.",
