fastMAD {ccaPP}

Fast implementation of the median absolute deviation

Description

Compute the median absolute deviation with a fast C++ implementation. By default, a multiplication factor is applied for consistency at the normal model.

Usage

fastMAD(x, constant = 1.4826)

Arguments

x

a numeric vector.

constant

a numeric multiplication factor. The default value yields consistency at the normal model.

Value

A list with the following components:

center

a numeric value giving the sample median.

MAD

a numeric value giving the median absolute deviation.

Note

Functionality for removing observations with missing values is currently not implemented.
