A Priori and Experimental Approximation of Simple Ratio Correlations

Abstract

Most measurements are of quantities that are in some sense ratios, but this requires no special consideration in correlation analysis or in studies of interdependence if the denominators of the ratios being compared are constants. That elevation is measured in units initially defined as some fraction of the distance from the equator to the pole and specific gravity as some multiple of the weight of an equivalent volume of water at a particular temperature and pressure, for instance, need not concern the petrologist seeking to characterize the relation between the elevations of a set of samples in a sill and their specific gravities. Indeed, without such scaling parameters it is difficult to see how questions of this kind could be answered, or even asked.
