Huber robust statistics

WebThe “Huber estimator” introduced in Huber ( 1973) was one of the first robust estimation methods applied to linear models. Basically, this estimator is a weighted version of the least-squares estimate with weights of the form: \ [ w_ {i} = \min \left (1,\frac {c} { r_ {i} }\right) \] WebWe suggest a novel criterion that allows analysing robustness of the test. We show that the main factor influencing these characteristics is the coefficients of variation (CV) of the TBEs. Thus just by using CV of the TBEs, we may conclude whether the test is robust or not. We also suggest approach of handling the case when test for pair of ...

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 ...
