WebBellin et al. [1994] propose a convergence criterion based on the quantity d2X n =(X n X n 1) 2, where X n is a target sample moment at a point, and n is the sample size, i.e., the number of Monte Carlo simulations. The authors consider the process to have reached convergence when the spatial average of d2X n over the whole computational domain ...
