Chinese Japanese Korean Vietnamese. As a result, it is unclear whether the methods can be reliably used on radiocarbon-dated time-series. The Analysis of Time Series: Quantifying the Influence of Climate on Human Conflict. This parameter was intended to help us determine whether having more dates improved regression results. Autocorrelation leads to dependence among the observations in a time-series, which violates another common statistical assumption, namely that observations are independent.
Exploring these two potential research avenues would help us to determine the limits of the PEWMA method, a method with considerable potential to deepen our insights into past human-environment interaction. The experiments involved creating thousands of pairs of artificial palaeoclimatic and archaeological time-series with known relationships and then testing for those relationships with the PEWMA method. Renfrew, C. Yet it has been argued that the utility of analytical solutions over numerical methods may vary inversely with the availability of computer technology. To determine this, a blank sample of old, or dead, carbon is measured, and a sample of known activity is measured.
