WebThe uncertainty that remains after the best possible analysis has been under-taken is what we call residual uncertainty—for example, the outcome of an ongoing regulatory debate … WebOptimization problems of this form will involve evaluation of a measure of residual uncertainty, and in Sect. 4 we present an approach for approximating this quantity. We implement this in Sect. 5 to develop an efficient numerical procedure for the one-step lookahead case, which we illustrate through a series of examples in Sect. 6 .
