Webb22 dec. 2006 · The famous “Slutsky Theorem” which argued that if a statistic converges almost surely or in probability to some constant, then any continuous function of that statistic also converges in the same manner to some function of that constant – a theorem with applications all over statistics and econometrics – was laid out in his 1925 paper. WebbShowing Convergence in Distribution Recall that the characteristic function demonstrates weak convergence: Xn X ⇐⇒ Eeit T X n → Eeit T X for all t ∈ Rk. Theorem: [Levy’s Continuity Theorem]´ If EeitT Xn → φ(t) for all t in Rk, and φ : Rk → Cis continuous at 0, then Xn X, where Eeit T X = φ(t). Special case: Xn = Y . data factory triggers

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.
