A method that is highly accurate and e cient for some problems, but performs poorly on others, is unreliable and therefore not likely to be used in applications, even if any alternative is not as accurate and e cient. The user of a numerical method needs to know that the result produced can be trusted.

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. One motivation is to produce statistical methods that are not unduly affected by outliers. Another motivation is to provide methods with good performance when ther…
