Estimation of Graded Response Model Parameters Using MULTILOG.
Baker, Frank B.
Applied Psychological Measurement, v21 n1 p89-90 Mar 1997
Describes an idiosyncracy of the MULTILOG (D. Thissen, 1991) parameter estimation process discovered during a simulation study involving the graded response model. A misordering reflected in boundary function location parameter estimates resulted in a large negative contribution to the true score followed by a large positive contribution. These did not cancel each other. (SLD)
