A Procedure for Dimensionality Analyses of Response Data from Various Test Designs
Zhang, Jinming - In: Psychometrika 78 (2013) 1, pp. 37-58
In some popular test designs (including computerized adaptive testing and multistage testing), many item pairs are not administered to any test takers, which may result in some complications during dimensionality analyses. In this paper, a modified DETECT index is proposed in order to perform...
