“How is the weighted mix calculated?
The main estimates shown are moving averages of three years, which smoothen stark differences in estimates between years due to random error (e.g. sampling). When multiple data points for a given year are available, the main estimate presented is the simple mean that is weighted by the inverse of the standard errors. This is a common weighting technique to give more weight to more precise estimates.”
