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. In probability theory, Slutsky’s theorem extends some properties of algebraic operations on convergent sequences of real numbers to sequences of random variables. The theorem was named after Eugen Slutsky. Slutsky's theorem is also attributed to Harald Cramér.

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.
