Public Methods

Method	Description
AbsoluteLinkFunction ( ) : System	Creates a new Absolute link function.
AbsoluteLinkFunction ( double beta ) : System	Creates a new Absolute link function.
Clone ( ) : object	Creates a new object that is a copy of the current instance.
Derivative ( double x ) : double	First derivative of the Inverse function. The first derivative of the absolute link function is given by `f'(x) = B`.
Derivative2 ( double y ) : double	First derivative of the Inverse function expressed in terms of it's output. The first derivative of the absolute link function in terms of y = f(x) is given by `f'(y) = B`.
Function ( double x ) : double	The Absolute link function. The absolute link function is given by `f(x) = abs(x) / b`.
Inverse ( double x ) : double	The mean function. The inverse absolute link function is given by `g(x) = B * abs(x)`.
Log ( double x ) : double	The logarithm of the inverse of the link function.
