winsorize_mad {rempsyc}

Winsorize based on the absolute median deviation

Description

Winsorize (bring extreme observations to usually +/- 3 standard deviations) data based on median absolute deviations instead of standard deviations.

Usage

winsorize_mad(x, criteria = 3)

Arguments

x

The vector to be winsorized based on the MAD.

criteria

How many MAD to use as threshold (similar to standard deviations)

Details

For the easystats equivalent, use: datawizard::winsorize(x, method = "zscore", threshold = 3, robust = TRUE).

Value

A numeric vector of winsorized data.
