Abstract: This paper deals with the estimate of errors introduced by finite sampling in Monte Carlo evaluation of functionals of stochastic processes. To this end we introduce a metric d over the space of probability measures which induces a topology finer than the weak topology. For any two measures [mu], v, this metric allows to bound /vb - /vb, uniformly over a large class of C1-functions f, by a quantity which can be computed by a finite number of calculations. In the case v = [mu]n, the empirical distribution of order n of [mu], we can compute the minimum sample size that will ensure that this quantity will be smaller than any given [var epsilon], at any chosen confidence level. As an application we control the rate of convergence of an approximating scheme for obliquely reflecting Brownian motion on a half-plane by a Monte Carlo evaluation of two significant functionals on the path space.
