Class PriorConditionalCombiner

java.lang.Object

org.drip.execution.bayesian.PriorConditionalCombiner

public class PriorConditionalCombiner
extends java.lang.Object

PriorConditionalCombiner holds the Distributions associated with the Prior Drift and the Conditional Price Distributions. It uses them to generate the resulting Joint, Posterior, and MAP Implied Posterior Distributions. The References are: - Bertsimas, D., and A. W.
