MCD Algorithm:https://wis.kuleuven.be/stat/robust/papers/2010/wire-mcd.pdf

An object for detecting outliers in a Gaussian distributed dataset.

the key to the question is the algorithm for the minimum covariance determinant estimator(MCD).



Outlier detection from covariance estimation may break or not perform well in high-dimensional settings. In particular, one will always take care to work with n_samples > n_features ** 2.
