A comparison of two observed-score equating methods that assume equally reliable, congeneric tests

MacCann, Robert G. (1989)
For the external-anchor test equating model, two observed-score methods are derived using the slope and intercept assumptions of univariate selection theory and the assumptions that the tests to be equated are congeneric ...

Congeneric modeling of reliability using censored variables

Brown, R. L. (1989)
This paper explores the use of Jöreskog’s (1970) congeneric modeling approach to reliability using censored quantitative variables, and discusses the compound problem of non-normality and attenuation that occurs when ...

Unidimensional IRT calibration of compensatory and noncompensatory multidimensional items

Ackerman, Terry A. (1989)
The characteristics of unidimensional ability estimates obtained from data generated using multidimensional compensatory models were compared with estimates from noncompensatory IRT models. Reckase, Carlson, Ackerman, ...

Distinguishing between measurements and dependent variables

Overall, John E. (1989)
Humphreys and Drasgow (1989b) recognize two types of dependent variables: the original measurements collected in an experiment and mathematical variables that are subjected to statistical analysis. Overall and Woodward ...

Contradictions can never a paradox resolve

Overall, John E. (1989)
The fact that difference scores tend to be less reliable than the original measurements from which they are calculated should not be a matter of concern in testing the significance of treatment-induced change. The ...
