L-estimator — In robust statistics, an L estimator is an estimator which equals a linear combination of order statistics of the measurements.Consider, for example, the median. Given n measurements x 1, ldots, x n, where n is odd, the median equals x… … Wikipedia
Winsorising — or Winsorization is the transformation of statistics by transforming extreme values in the statistical data, and is named for the engineer turned biostatistician Charles P. Winsor (1895 ndash;1951).The distribution of many statistics can be… … Wikipedia

Robust statistics — provides an alternative approach to classical statistical methods. The motivation is to produce estimators that are not unduly affected by small departures from model assumptions. Contents 1 Introduction 2 Examples of robust and non robust… … Wikipedia
Truncated mean — A truncated mean or trimmed mean is a statistical measure of central tendency, much like the mean and median. It involves the calculation of the mean after discarding given parts of a probability distribution or sample at the high and low end,… … Wikipedia
Absolute deviation — In statistics, the absolute deviation of an element of a data set is the absolute difference between that element and a given point. Typically the point from which the deviation is measured is a measure of central tendency, most often the median… … Wikipedia
Errors-in-variables models — In statistics and econometrics, errors in variables models or measurement errors models are regression models that account for measurement errors in the independent variables. In contrast, standard regression models assume that those regressors… … Wikipedia
