Median Absolute Deviation

Description

mad provides a scale estimate based on the median absolute deviation. The actual value calculated is constant * (median(abs(x - center))) with the default value of center being median(x).

If na.rm is TRUE then NA values are stripped from x before computation takes place. If this is not done then an NA value in x will cause mad to return NA.

Usage

mad(x, center, constant=1.4826, na.rm=FALSE)
