# Examples of convergence in distribution using CDF directly [duplicate]

I find very interesting the example that if we let $$Q_n$$ be the maximum of n i.i.d. with distribution $$U[0,\alpha]$$, then $$n(Q_n - \alpha)$$ converges to an exponential distribution. See e.g. here for this solution.

What other examples are there that are similar in the sense that they are (1) non-trivial and (2) they don't need to rely on other theorems (e.g., like CLT or delta method), but rather can be found directly from taking the limit of the CDF.

I'm interested in both discrete and continuous examples.

• You ought to clarify that the maximum of iid uniforms does not converge to an exponential distribution: you implicitly suppose the maximum has been appropriately recentered and rescaled along the way. This is a key operation. – whuber Nov 15 '18 at 13:37
• @whuber thank you for comment. I will clarify. Even though post marked as duplicate, you are right I should not spread bad information. – Emp Proc Nov 15 '18 at 16:08
