Influence of Test and Person Characteristics on Nonparametric Appropriateness Measurement.
Peer reviewed Peer reviewed
Meijer, Rob R.; And Others – Applied Psychological Measurement, 1994
The power of the nonparametric person-fit statistic, U3, is investigated through simulations as a function of item characteristics, test characteristics, person characteristics, and the group to which examinees belong. Results suggest conditions under which relatively short tests can be used for person-fit analysis. (SLD)

Reliability Estimation for Single Dichotomous Items Based on Mokken's IRT Model.
Peer reviewed Peer reviewed
Meijer, Rob R.; And Others – Applied Psychological Measurement, 1995
Three methods based on the nonparametric item response theory (IRT) of R. J. Mokken for the estimation of the reliability of single dichotomous test items are discussed. Analytical and Monte Carlo studies show that one method, designated "MS," is superior because of smaller bias and smaller sampling variance. (SLD)
