Each element of the output array is the mean absolute deviation of … Median Absolute Deviation Description. Compute the median absolute deviation, i.e., the (lo-/hi-) median of the absolute deviations from the median, and (by default) adjust by a factor for asymptotically normal consistency. Usage mad(x, center = median(x), constant = 1.4826, na.rm = FALSE, low = FALSE, high = FALSE) Arguments 7. I'm trying to implement a procedure to evaluate the median absolute deviation of a set of numbers (usually obtained via a GROUP BY clause).

For the example {2, 2, 3, 4, 14}: 3 is the median, so the absolute deviations from the median are {1, 1, 0, 1, 11} (reordered as {0, 1, 1, 1, 11}) with a median of 1, in this case unaffected by the value of the outlier 14, so the median absolute deviation (also called MAD) is 1. When calculating the median absolute deviation (MAD) via fun.data = median_mad using the function stat_summary in ggplot2, the constant factor is set to 1.4826 by default.

The median absolute deviation (MAD) [65] is a measure of the variance of a data sample; this estimator is popular because of its robustness with respect to outliers. Let y be the noisy observation of the signal, then the MAD is defined by
