Winsorization is a statistical technique used to replace extreme values in a dataset with less extreme values. This approach can help to reduce the impact of outliers on the analysis and improve the accuracy of the results. However, there are alternative methods that can achieve similar outcomes. Some synonyms for Winsorization include trimming, clipping, and capping, which all involve modifying the data to mitigate the effects of extreme values. Other methods such as data transformation, robust regression, and non-parametric methods can also address outliers in different ways. Ultimately, the method chosen will depend on the specific data and analytical needs.
