Portmanteau's theorem
WebNov 22, 2024 · Central Limit Theorem. 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. WebJun 7, 2024 · Continuous mapping theorem.
