Accord.Statistics.Links.AbsoluteLinkFunction.Derivative2 C# (CSharp) Method

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.

public Derivative2 ( double y ) : double
y	double	The reverse transformed value.
return	double

        public double Derivative2(double y)
        {
            return B;
        }
