asymmetric_tanh: asymmetric_tanh

In Mufabo/Rrobustsp: Robust Signal Processing

asymmetric_tanh

Description

Computes the smoothed asymmetric tanh score and its derivative.

Usage

asymmetric_tanh(sig, c1, c2, x1)

Arguments

sig	: the signal
c1	: first clipping point
c2	: second clipping point
x1	: smoothing parameter to make the score function continuous

Value

phi : asymmetric tanh score function

phi_point : derivative of asymmetric score function
