rrcov: Scalable Robust Estimators with High Breakdown Point

WebA breakdown point is the point after which an estimator becomes useless. It is a measure of robustness; The larger the breakdown point, the better the estimator. If an estimator has a high breakdown point, it may be called a resistant statistic. There are two types of breakdown points: finite sample breakdown points and asymptotic breakdown points.
