A Simplex Fitting Approach to Dimensionality Assessment of Binary Data Matrices.

Roznowski, Mary; And Others

Educational and Psychological Measurement, v54 n2 p263-83 Sum 1994

A Monte Carlo investigation of simplex fitting as a method of determining the dimensionality of binary data matrices was conducted. Examination of the fit of correlation matrices with a known factor structure to correlation matrices that represent the perfect simplex shows that simplex fitting is a feasible approach under some circumstances.
