I need to characterize the mean, CV and skewness of my observed data (it is gamma-like distributed). This data is an artifact (outliers) enriched, so I decide to use robust statistics: median, interquartile range divided to median, and medcouple.
I have two questions:
1) Is it correct and commonly used robust statistics? (The biggest doubt I have about using IQR/median instead of CV).
2) Could you help me with references for my or your robust CV estimator?
