WebAccordingly, robust methods have been created to modify least squares schemes so that the outliers have much less influence on the final estimates. One of the most satisfying … Robust statistics are statistics with good performance for data drawn from a wide range of probability distributions, especially for distributions that are not normal. Robust statistical methods have been developed for many common problems, such as estimating location, scale, and regression parameters.
