Consistency of Rasch Model Parameter Estimation: A Simulation Study.
van den Wollenberg, Arnold L.; And Others
Applied Psychological Measurement, v12 n3 p307-13 Sep 1988
The unconditional--simultaneous--maximum likelihood (UML) estimation procedure for the one-parameter logistic model produces biased estimators. The UML method is inconsistent and is not a good alternative to conditional maximum likelihood method, at least with small numbers of items. The minimum Chi-square estimation procedure produces unbiased estimates and is computationally fast. (TJH)
