public class VarianceGammaProcessDiffPCASymmetricalBridge
extends VarianceGammaProcessDiffPCA

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

Constructs a new VarianceGammaProcessDiffPCASymmetricalBridge 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 GammaProcessPCASymmetricalBridge's. The other parameters are set as in VarianceGammaProcessDiff.
