Unidimensional IRT Calibration of Compensatory and Noncompensatory Multidimensional Items.

Ackerman, Terry A.

Applied Psychological Measurement, v13 n2 p113-27 Jun 1989

The characteristics of unidimensional ability estimates obtained from data generated using multidimensional compensatory models were compared with estimates from non-compensatory item response theory (IRT) models. The least squares matching procedures used represent a good method of matching the two multidimensional IRT models. (TJH)
