One way of interpreting the convergence of a sequence Xn to X is to say that the ''distance'' between X and Xn is getting smaller and smaller.

A sequence of random vectors is convergent in mean-square if and only if all the sequences of entries of the random vectors are. Proposition ...

By Chebysjev's inequality we see that convergence in mean square implies convergence in probability. 2 Mean Ergodic Theorem. Although the definition of converge ...

When Xn converges in r-th mean to X for r = 2, we say that Xn converges in mean square (or in quadratic mean) to X. Convergence in the r-th mean, for r ≥ 1 ...
