Peer reviewedKnol, Dirk L.; Berger, Martijn P. F. – Multivariate Behavioral Research, 1991
In a simulation study, factor analysis and multidimensional item response theory (IRT) models are compared with respect to estimates of item parameters. For multidimensional data, a common factor analysis on the matrix of tetrachoric correlations performs at least as well as the multidimensional IRT model. (SLD)
