Interface MultiVariateRealization

All Superinterfaces:

MultiVariateRealization, MultiVariateTimeSeries<java.lang.Double>, TimeSeries<java.lang.Double,Vector>

public interface MultiVariateRealization
extends MultiVariateRealization

This interface defines the realization for a multivariate stochastic process, as well as the Iterator for generating (reading) the realization.

According to the Lévy–Khintchine representation, for a stochastic process, we have

the absolutely continuous part such that the increment dB is proportional to the square root of time increment dt
