Reliability of Test Scores in Nonparametric Item Response Theory.

Sijtsma, Klaas; Molenaar, Ivo W.

Psychometrika, v52 n1 p79-97 Mar 1987

Three methods for estimating reliability are studied within the context of nonparametric item response theory. Two were proposed originally by Mokken and a third is developed in this paper. Using a Monte Carlo strategy, these three estimation methods are compared with four "classical" lower bounds to reliability. (Author/JAZ)
