With this in mind, we carried out a big simulation examine to research the impression of chronological uncertainty on a doubtlessly helpful time-series method. The technique is a type of regression involving a prediction algorithm referred to as the Poisson Exponentially Weighted Moving Average (PEMWA). It is designed for use with rely time-series knowledge, which makes it relevant to a variety of questions about human-environment interaction in deep time. Our simulations counsel that the PEWMA technique can usually correctly determine relationships between time-series despite chronological uncertainty. When two time-series are correlated with a coefficient of zero.25, the tactic is prepared to establish that relationship accurately 20–30% of the time, providing the time-series contain low noise levels. With correlations of around 0.5, it is capable of appropriately figuring out correlations regardless of chronological uncertainty more than 90% of the time.
