The Importation Model Perspective on Inmate Social Roles: an Empirical Test.

This paper suggests a new way of applying "Proportional-Reductions-in-Error" related measures (i.e., Gamma, dyx, dxy, and Kendall's Tau's) to link logical forms of hypotheses to types of ordinal measures of association. First, the basic form of associations for ordinal data are examined. Second, the analytical properties of "P-R-E" related measures are investigated. Finally, it is proposed that "P-R-E" related measures be used in testing the logical form of the relationship between variables implied in a hypothesis. [ABSTRACT FROM AUTHOR]
