but we have temporarily restricted your access to the Digital Library.Your activity appears to be coming from some type of automated process.It is not the most stable possible calculation, but is sufficient for almost all purposes.If stability does become an issue for you there are some other things that can be done.A clever solution to this problem for streaming mean and variance computation was proposed by West in 1979.In his algorithm the summed quantities are controlled to be on average of comparable size.To ensure the availability of the Digital Library we can not allow these types of requests to continue.The restriction will be removed automatically once this activity stops.

In the univariate case, you only need store a few values.

Furthermore, the method computes a running variance.

That is, the method computes the variance as the ‘s arrive one at a time.

Our approach to making such comparisons strikes some as highly counterintuitive, and noticeably different from that of other “prioritization” projects such as Copenhagen Consensus.

Rather than focusing on a single metric that all “good accomplished” can be converted into (an approach that has obvious advantages when one’s goal is to maximize), we tend to rate options based on a variety of criteria using something somewhat closer to (while distinct from) a “1=poor, 5=excellent” scale, and prioritize options that score well on multiple criteria.
