HyperbolicNormalizer

public HyperbolicNormalizer(double mediumValue,
                            double x,
                            double y,
                            boolean reciproc)

Create a new instance of HyperbolicNormalizer.

Parameters:

mediumValue - Input value whose mormalization result is 0.5.

x - X coordinate of a point on the graph of the normalization function of normalize(). Must be != 0.5.

y - Y coordinate (value) corresponding to x. 0 < y < 1

Method Detail

normalize

public double normalize(double value)

Return a normalized value. Input can be < or > 0.

Returns:

A positive value in the range from 0 to 1.

normalize2

public double normalize2(double value)

Return a normalized value. Input must be > 0.

Returns:

A positive value in the range from 0 to 1.
