convergence in distribution
A sequence of distribution functions![]()
converges weakly to a distributionfunction if for each point at which is continuous.
If the random variables![]()
have associated distribution functions, respectively, then we say that converges in distribution
to, and denote this by .
This definition holds for joint distribution functions![]()
and random vectors as well.
This is probably the weakest of convergence of random variables. Some results involving this of convergenceare the central limit theorems![]()
, Helly-Bray theorem, Paul Lévy continuity theorem, Cramér-Wold theorem and Scheffé’s theorem.
