On ratio scales

Measurement, 2013
Abstract In the past, ratio scales have been a highly controversial issue between physicists and psychologists as regards the need for an empirical addition operation in order to attain them. This aspect is critical since such an operation is often unavailable in psychophysical experiments, as it is in physics, due to its intensive properties.

Alternative Power Laws for Ratio Scaling

Psychometrika, 1966
To take account of the observed lack of fit of the power law near thresh-old intensities, two different modifications of the power law have been proposed by various investigators. In this paper, both of these two laws are derived as a special case of a generalized power function for ratio scaling.

Scale ratios, statistical symmetries and intermittency

Europhysics Letters (EPL), 1998
Existence (or lack) of preferred scale has largely been used as a useful guide to investigate statistics of stochastic extended systems. In particular, widespread use of power laws in literature actually comes from the fact that these are the only single scale functions pertaining to systems relying on no preferred scale.
