Trimmed comparison of distributions
WebNov 25, 2024 · As a non-parametric test, the KS test can be applied to compare any two distributions regardless of whether you assume normal or uniform. In practice, the KS test is extremely useful because it is efficient and effective at distinguishing a sample from another sample, or a theoretical distribution such as a normal or uniform distribution. WebThe distributions sometimes are heavily contaminated and sometimes not. Usually they follow something similar to a log-normal or possibly mixed log-normal distribution, but often the data is "all over the place". I've looked at the mean, 5% trimmed mean, 10% trimmed mean and 20% trimmed mean.

The mean is 0.005, the median is -0.010, and the mode is -0.144 (the mode is computed as the midpoint of the histogram interval with the highest peak). ... For better visual comparison with the other data sets, we restricted the histogram of the Cauchy distribution ...

WebAug 27, 2024 · The trimmed mean acts as a compromise, allowing us to establish a relatively low SE for both normal and non-normal distributions of data (Wilcox, 2005). Another point of comparison for the trimmed mean against the median is that, with the median we are heavily protected against outliers, as we take only a single value in a middle. Web& Gasko, 1983; Wilcox, 1995). The x% trimmed mean has a breakdown point of x% for the chosen level of x. For example, a mean trimmed 50% is computed by discarding the lower and higher 25% of the scores and taking the mean of the remaining scores. The median is the mean trimmed 100% and the arithmetic mean is the mean trimmed 0%.
WebAug 5, 2024 · We survey some of the recent advances in mean estimation and regression function estimation. In particular, we describe sub-Gaussian mean estimators for possibly heavy-tailed data in both the univariate and multivariate settings. We focus on estimators based on median-of-means techniques, but other methods such as the trimmed-mean …
