Description

Median Absolute Deviation

Usage

mad(x, na.rm = FALSE)

Arguments

x	numeric vectors whose median absolute deviation is wanted
na.rm	logical; if true, any NA and NaN's are removed from x before the quantiles are computed.

Details

MAD is computed by subtracting the median from each observation, taking the absolute value of each difference, and then computing the median.

Typically, MAD is divided by 0.6745. MADN = MAD / 0.6745

Examples

x <- c(12,45,23,79,19,92,30,58,132)
mad(x)
