Method Description
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 identity 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 identity link function in terms of y = f(x) is given by f'(y) = B.

Function ( double x ) : double

The Identity link function.

The Identity link function is given by f(x) = (x - A) / B.

IdentityLinkFunction ( ) : System

Creates a new Identity link function.
IdentityLinkFunction ( double beta, double constant ) : System

Creates a new Identity link function.
Inverse ( double x ) : double

The mean function.

The inverse Identity link function is given by g(x) = B * x + A.

Log ( double x ) : double

The logarithm of the inverse of the link function.
