The notion of depth provides a route to possible analogs of the sample median and quantiles—beyond the univariate location model. Unlike other approaches, depth substantially elaborates on the order structure of the sample space.

Webin Section 6 we argue that the connection between breakdown and equivariance is fragile. 1.2. Breakdown points and equivariance. The notion of breakdown point was introduced by Hampel (1968, 1971).

WebJun 19, 2013 · The breakdown point of OLS estimator equals to the inverse of the sample size which would tend to zero as the sample size tends to grow large [6]. Unlike OLS estimator, robust regression provides robust regression estimators even in the presence of multiple outliers.
