Webis continuous, then . Y. n. is said to have a . limiting distribution with cdf. F(y). • Definition of convergence in distribution requires only that limiting function agrees with cdf at . its points of continuity. lim ( )() n. n. FyF y. →∞ = WebIt may appear obvious that a limit is unique if one exists, but this fact requires proof. Proposition 3.11. If a sequence converges, then its limit is unique. Proof. Suppose that (x n) is a sequence such that x n!xand x n!x0as n!1. Let >0. Then there exist N;N02N such that jx n xj< 2 for all n>N; jx n x0j< 2 for all n>N0:

A sequence is bounded above if and only if supL < ∞. A sequence is bounded below if and only if inf L > −∞. A sequence is bounded if both inf L and supL are real numbers (i.e. finite). A sequence has limit ...
