Summary

A number of summary measures describing the agreement between methods have been proposed in the literature. Most of these are (intended to be) scale-free in the sense that the absolute scale of measurement does not enter into the measure. This seems to be an attempt to define purely statistical machinery for comparing methods. The measures based on correlation are all by definition irrelevant in method comparison studies, because they involve the sample variation, that is, the variation between items in the sample.
