public class VarianceGammaProcessDiffPCABridge
extends VarianceGammaProcessDiffPCA

Same as VarianceGammaProcessDiff, but the two inner GammaProcess'es are of the type PCABridge. Also, generatePath(double[] uniform01) distributes the lowest coordinates uniforms to the inner GammaProcessPCABridge according to their eigenvalues.

Constructor Summary

VarianceGammaProcessDiffPCABridge(double s0, double theta, double sigma, double nu, RandomStream stream)
Constructs a new VarianceGammaProcessDiffPCABridge with parameters θ = theta, σ = sigma, ν = nu and initial value S(t₀) = s0.

VarianceGammaProcessDiffPCABridge

public VarianceGammaProcessDiffPCABridge(double s0,
                                         double theta,
                                         double sigma,
                                         double nu,
                                         RandomStream stream)

Constructs a new VarianceGammaProcessDiffPCABridge with parameters θ = theta, σ = sigma, ν = nu and initial value S(t₀) = s0. There is only one RandomStream here which is used for the two inner GammaProcessPCABridge's. The other parameters are set as in VarianceGammaProcessDiff.
