WebbIn Theorem 1 of the paper by [BEKSY] a generalisation of a theorem of Slutsky is used. In this note I will present a necessary and su–cient condition that assures that whenever X n is a sequence of random variables that converges in probability to some random variable X, then for each Borel function fwe also have that f(X n) tends to f(X) in WebbABSTRACT. For weak convergence of probability measures on a product of two topological spaces the convergence of the marginals is certainly necessary. If however the marginals on one of the factor spaces converge to a one-point measure, the condition becomes sufficient, too. This generalizes a well-known result of Slutsky. ipo coming up 2021 tips rank https://jshefferlaw.com

WebbNote. In this section we define convergence in distribution by considering the limit of a sequence of cumulative distribution functions. We relate convergence in probability and convergence in distribution (see Example 5.2.B and Theorem 5.2.1). We state several theorems concerning convergence in distribution of sequences of random variables.
