public class DynamicConvergenceReport
extends AbstractMarketStatsReport

A historicalDataReport that keeps track of the convergence of transaction prices, computing the coefficient of convergence Vernon Smith used. The equilibrium price is recomputed at the end of each day, thus this class can be used to keep track of theoretically available surplus even when supply and demand are changing over time. Each agent is assumed to be hypothetically able to trade the specified quantity of units in each day.
