wfu: Weight function (for Mahalabobis distances)

Description

Function of the elements of md, which is 1 for arguments smaller than ca, 0 for arguments larger than ca2 and linear (default: continuous) in between.

Thought for use in fixmahal.

Usage

wfu(md, ca, ca2, a1 = 1/(ca - ca2), a0 = -a1 * ca2)

Arguments

md

vector of positive numericals.

ca

positive numerical.

ca2

positive numerical.

a1

numerical. Slope.

a0

numerical. Intercept.

Value

A vector of numericals between 0 and 1.
