WebbComparison of Slutsky Theorem with Jensen’s Inequality highlights the di erence between the expectation of a random variable and probability limit. Theorem A.11 Jensen’s Inequality. If g(x n) is a concave function of x n then g(E[x n]) E[g(x)]. The comparison between the Slutsky theorem and Jensen’s inequality helps WebbConvergence in Probability. A sequence of random variables X1, X2, X3, ⋯ converges in probability to a random variable X, shown by Xn p → X, if lim n → ∞P ( Xn − X ≥ ϵ) = 0, for all ϵ > 0. Example. Let Xn ∼ Exponential(n), show that Xn p → 0. That is, the sequence X1, X2, X3, ⋯ converges in probability to the zero random ...

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. WebbThe probability of observing a realization of {xn} that does not converge to θis zero. {xn} may not converge everywhere to θ, but the points where it does not converge form a zero measure set (probability sense).
