MAD (about median) vs. quantile-based alternatives for classical standard deviation, skewness, and kurtosis

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
In classical probability and statistics, one computes many measures of interest from mean and standard deviation. However, mean, and especially standard deviation, are overly sensitive to outliers.
