WebbSlutsky's theorem From Wikipedia, the free encyclopedia . In probability theory, Slutsky’s theorem extends some properties of algebraic operations on convergent sequences of real numbers to sequences of random variables. [1] The theorem was named after Eugen Slutsky. [2] Slutsky's theorem is also attributed to Harald Cramér. [3] WebbProof. This theorem follows from the fact that if Xn converges in distribution to X and Yn converges in probability to a constant c, then the joint vector ( Xn, Yn) converges in …

WebbConvergence in probability is stronger than convergence in distribution. A sequence of random variables X i converges in probability to X if for lim n → ∞ P ( X n − X ≥ ϵ) = 0 for every ϵ > 0. This is denoted as X n → p X. We can also write this in similar terms as the convergence of a sequence of real numbers by changing the formulation. WebbSlutsky’s theorem is used to explore convergence in probability distributions. It tells us that if a sequence of random vectors converges in distribution and another sequence … WebbComparison of Slutsky Theorem with Jensen’s Inequality highlights the di erence between the expectation of a random variable and probability limit.
