Huber robust statistics
WebAbstract. This is a selective review on robust statistics, centering on estimates of location, but extending into other estimation and testing problems. After some historical remarks, several possible concepts of robustness are critically reviewed. Three important classes of estimates are singled out and some basic heuristic tools for assessing ... WebIt has excellent robustness to outliers. The "price" of robustness is about 25%. The 5%-trimmed average is another possible method. Here you throw away the 5% highest and 5% lowest values, and then take the mean (average) of the result. This is less robust to outliers: as long as no more than 5% of your data points are corrupted, it is good ...

Webof robustness is due to Huber (1964) and was expounded in Huber (1981). Huber’s approach is functional analytic and he was the first to investigate the behaviour of a statistical functional over a full topological neighbourhood of a model instead of restricting the investigation to other parametric families as in (1).
