I'll post to no particular schedule on whatever currently catches my interest. It'll probably be mostly maths or maths-related stuff.
Suppose we want to assign scores to a large collection of objects – too large for a single assessor to deal with. We are pretty much forced into having a panel of assessors, each of whom assesses some small collection of the objects. Then the question is, how do we combine their scores to obtain final scores?
There are various possible approaches, depending on whether our final objective is an overall ranking of the objects, or an actual score for each object.
