Moment-matching
Webmoment-based filters by proving that approximations that use moment matching are not just ad-hoc methods but provide an optimal approximation in the sense that the information loss is minimized. Furthermore, our results are of interest for the research area of minimum divergence filtering [22], [23], where Web37.10. Moment-matching scenarios. In this section we discuss how to obtain scenario-probability distributions which display the desired expectations and covariances. Let us consider a set of ¯n market variables X= (X1,…,X¯n)' distributed according to a fully general scenario-probability distribution X∼{x(j),p(j)}¯ȷ j=1 ( 37.239 ).
