"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… " - The portmanteau theorem

WebbIt follows from the portmanteau theorem that $\E(g({\bb X}^{(n)}))\to \E(g({\bb X}))$, proving the second statement. To prove the third statement, note that we have with probability 1 a continuous function of a convergent sequence. WebbWe will need a particular statement from the portmanteau theorem: that convergence in distribution is equivalent to Fix an arbitrary closed set F ⊂ S′. Denote by g−1 ( F) the pre-image of F under the mapping g: the set of all points x ∈ S such that g ( x )∈ F. Consider a sequence { xk } such that g ( xk )∈ F and xk → x.

Take g(f) := sup 0 t 1 f(t). WebbBy the Portmanteau theorem, the constant net yj = y converges to 5. Thus the narrow closure A of {y: y E A} in M1 (S X T) is a subset of A. As 5( f E g) = y( f E g), we can apply Theorem 1 to A and obtain the desired result. E1 COROLLARY 3. In the following cases, Corollary 2 holds: (a) S and T are
