Constructor Detail

NortaInitDisc

public NortaInitDisc(double rX,
                     DiscreteDistributionInt dist1,
                     DiscreteDistributionInt dist2,
                     double tr)

Constructor of the abstract class. It can be called only by the constructors of subclasses of NortaInitDisc.

Method Detail

computeCorr

public abstract double computeCorr()

This method computes and returns the correlation ρ_Z. Every subclass of NortaInitDisc must implement it.

computeParams

public void computeParams()

This method computes the following inputs of the two marginal distributions: m₁ and m₂, mu1, mu2, sd1, sd2, and the vectors p1, p2, z1 and z2. Every subclass of NortaInitDisc must call it.

integ

public double integ(double r)

Computes the function value g_r for each correlation.

deriv

public double deriv(double r)

Computes the first derivative of function g_r for each correlation.

toString

public String toString()

Overrides:

toString in class Object
