The Trimmed Mean and Winsorized Mean tables, as shown in Figure 38.17, contain the following statistics: (1/2)Percent is the percentage of observations trimmed or Winsorized at each end. In statistics, a trimmed estimator is an estimator derived from another estimator by excluding some of the extreme values, a process called truncation. This is generally done to obtain a more robust statistic, and the extreme values are considered outliers. Trimmed estimators also often have higher efficiency for mixture distributions and heavy-tailed distributions than the corresponding untrimmed estimator, at the cost of lower efficiency for other distributions, such as the normal di… fgv whatsapp
