FIELD-SCALE VARIABILITY OF SOIL PROPERTIES IN CENTRAL IOWA SOILS

, 1994
Spatial distributions of soil properties at the field and watershed scale may affect yield potential, hydrologic responses, and transport of herbicides and NO to surface or groundwater.

THE GARNER‐ATTNEAVE THEORY OF RATIO SCALING

Scandinavian Journal of Psychology, 1967
The theory is shown to be logically and psychologically untenable, being based on a first order phenomenological‐numerical (PN) relation which cannot exist. An alternative theory, not possessing this shortcoming because it involves a second order PN relation, explains both ratio and category 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.

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.

A Proposed Method for Absolute Ratio Scaling

Psychometrika, 1950
A method of ratio scaling is described for treating comparative judgments of paired stimuli. A method of comparative judgment developed by Metfessel is employed. Formulas for scale values and the solution of a sample problem are provided. The method is designed to provide internal-consistency checks on the scale values.

Sustainable Synthesis and Assembly of Biomass‐Derived B/N Co‐Doped Carbon Nanosheets with Ultrahigh Aspect Ratio for High‐Performance Supercapacitors

, 2016
The practical application of graphene has still been hindered by high cost and scarcity in supply. It boosts great interest in seeking for low‐cost substitute of graphene for upcoming usage where extremely physical properties are not absolutely critical.

Nonparametric Estimation of Ratio of Scale Parameters

Journal of the American Statistical Association, 1977
Abstract Let X 1, …, X m and Y 1, …, Y n be independent random variables from two continuous distributions F (σ1 −1 (x − v)) and F (σ2 −1 (x − η)), respectively, where ν and η are medians and σ1 and σ2 are scale parameters. Explicit forms of estimators of the ratio of scale parameters are obtained based on Ansari-Bradley, modified Ansari-Bradley ...

Modelling pairwise comparisons on ratio scales

European Journal of Operational Research, 1995
Abstract Many ‘real world’ decision problems have multiple criteria on qualitative domains. Given the expectation that more and more of such problems will be modelled as MCDM problems involving scoring on subjective/qualitative domains, then there is a class of significant problems for which the evaluator will require an evaluation framework which ...
