The portmanteau theorem

WebbTo shed some light on the sense of a portmanteau theorem for unbounded measures, let us consider the question of weak convergence of inflnitely divisible probability measures „n, n 2 N towards an inflnitely divisible probability measure „0 in case of the real line R.

As we understand i.i.d. data and time series a bit better after part 1 of this mini-series, it is time to look at differences between them and the central limit theorem is a good start. The central limit theorem basically suggests that the sum of a sequence of random variables can be approximated by a normal distribution. optical style bar manchester ct https://iscootbike.com

WebbIt relies on the continuous mapping theorem (CMT), which in turns rests on several other theorems such as the Portmanteau Theorem. To avoid the rabbit hole of proving all necessary antecedent theorems, I simply introduce and state the continuous mapping theorem (CMT) here, and then show how this can be used to prove Slutsky’s Theorem.

Since in a metric space, a compact set is closed, the condition remains necessary. However, it's not sufficient. Consider E = R with the usual metric, P n := δ n and P any probability measure. Then for each compact K, P n ( K) = 0 for n ...
