A sequence of random variables X1, X2, X3, ⋯ converges in probability to a random variable X, shown by Xn p→ X, if limn→∞P(|Xn−X|≥ϵ)=0, for all ϵ>0. Example.

This lecture discusses convergence in probability, first for sequences of random variables, and then for sequences of random vectors.

In Example 3, Xn converges in probability. Now consider. E (Xn − 0). 2 = 0 ... • Convergence in probability implies convergence in distribution — so convergence.
