Test Equating: What, Why, How?
Research Quarterly for Exercise and Sport, 1998The purpose of this paper is to introduce test equating, including its concept, needs, and methods, to the field of physical education and exercise science. Both traditional and item response theory (IRT) equating methods, along with data collection designs, were described in detail, and the advantages and disadvantages of these methods were also ...

A Fresh Test of the Epstein Equations for Cylinders
Journal of Applied Mechanics, 1958Abstract Objections that have been raised against Epstein’s equations of motion for uniform cylindrical shells and the author’s extensions and conclusions from them are considered. A direct proof is offered that the equations must hold, and further reasons are given for believing that they can be used in practice, at least as a basis for

Test in a Structural Equation.
Econometrica, 1989Properties of t ratios associated with the limited information maximum likelihood, two-stage least squares, and ordinary least squares estimators in a structural form estimation are studied. The existence of moments of these t ratios, including the limited information maximum likelihood form, is proved first.

On chains of word equations and test sets
Bull. EATCS, 1999Summary: Ehrenfeucht's conjecture is equivalent with the ascending chain condition for word equations. A related conjecture concerns the descending chain condition for word equations. We show that if this conjecture holds then an arbitrary infinite language \(L\) possesses a finite subset \(F\) such that the language \(L-F\) is a disjoint union of its ...

Equating an adaptive test to a linear test
2005Two new methods for the equating of an adaptive test to a linear test are presented. The methods are based on the conditional distributions of the observed scores on the two tests, given the examinee’s ability. They are motivated by the fact that conditioning on the examinee’s ability is necessary to allow for differences between observed-score ...
