Our proof goes along the lines of the proof of the original portmanteau theorem and differs from the proof of Proposition 1.2.19 in [3].

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.

The convergence of sequences of probability measures that appears at ( a ) and at ( b ) of Theorem 1.1 in this paper is signi cantly more general than the convergence in the C b(X)-weak topology of M(X) that appears in the Portmanteau theorem (for details on the C b(X)-weak topology of M(X), see WebApr 23, 2006 · Abstract: We prove an analogue of the portmanteau theorem on weak convergence of probability measures allowing measures which are unbounded on an …
