Abstract: A method and machine for determining the likely value of an amount or amounts in the face of uncertainty. The invention relates to an improved method of forecasting or prediction. More specifically the use of resampling to obtain better predictions of unknown values through the consideration of uncertainty. The method can determine supply, demand, supply/demand gaps, price, cost, proportion, policy choice, amounts, quantities, levels, needs, requirements and other values that are difficult to determine due to the presence of one or more uncertainties.
