Abstract: A Monte Carlo investigation of simplex fitting as a method of determining the dimensionality of binary data matrices was carried out. The simplex is an index of dimensionality having considerable appeal on a priori grounds. The study was carried out to explore the adequacy of simplex fitting for estimating dimensionality of binary item pools. To achieve this objective, an examination was made of the fit of correlation matrices with known factor structure to a correlation matrix representing a perfect simplex.…
