Refinements of Stout's Procedure for Assessing Latent Trait Unidimensionality.
Nandakumar, Ratna; Stout, William
Journal of Educational Statistics, v18 n1 p41-68 Spr 1993
A detailed investigation is provided of Stout's statistical procedure (the computer program DIMTEST) for testing the hypothesis that an essentially unidimensional latent trait model fits observed binary item response data from a psychological test. Three refinements achieve greater power. The revised approach is validated using real data sets. (SLD)
