Guttman (1947) developed a scaling method in which the items measuring an attribute can be ordered according to the … strength of the attribute. The Guttman scaling model assumes that every member of the population belongs to a scale type and … contingency tables, pi-star can be applied to latent class models, including scaling models for dichotomous data.

This paper proposes a model of the US unemployment rate which accounts for both its asymmetry and its long memory. Our approach, based on the tests of Robinson (1994), introduces fractional integration and nonlinearities simultaneously into the same framework (unlike earlier studies employing a...
