Population Invariance and the Equatability of Tests: Basic Theory and the Linear Case.
Dorans, Neil J.; Holland, Paul W.
Journal of Educational Measurement, v37 n4 p281-306 Win 2000
Studied the degree to which equating functions failed to demonstrate population invariance across subpopulations, using two root-mean-square difference measures of the degree to which functions used to link two tests computed on subpopulations differ from the linking function for the whole population. Illustrated the ideas using data from the Scholastic Assessment Test I (SAT I) and a concordance study of SAT I and ACT Assessment scores. (SLD)
