In mathematics and statistics, weak convergence is one of many types of convergence relating to the convergence of measures. It depends on a topology on the underlying space and thus is not a purely measure theoretic notion. There are several equivalent definitions of weak convergence of a sequence of measures, some of which are (apparently) more general than others. The equivalence of these conditions is someti… Webb17 nov. 2013 · Lecture 7: Weak Convergence 3 of 9 3. limsup n mn(F) m(F), for all closed F S, Note: Here is a way to remember whether closed sets go together with the liminf or … candy cane christmas story free printableWebbTo shed some light on the sense of a portmanteau theorem for unbounded measures, let us consider the question of weak convergence of inﬂnitely divisible probability measures „n, n 2 N towards an inﬂnitely divisible probability measure „0 in case of the real line R.

If we replace the word "closed" by "compact" in the theorem, it won't be true. Since in a metric space, a compact set is closed, the condition remains necessary. However, it's not sufficient. Consider E = R with the usual metric, P n := δ n and P any probability measure. Then for each compact K, P n ( K) = 0 for n ...
