Applicability of the Rasch Model with Varying Item Discriminations
Dinero, Thomas E.; Haertel, Edward
Applied Psychological Measurement, 1, 4, 581-92, F 77
This research simulated responses of 75 subjects to 30 items under the Birnbaum model and attempted a fit to the data using the Rasch model. When item discriminations varied from a variance of .05 to .25, there was only a slight increase in lack of fit as the variances increased. (Author/CTM)
