Fitting Polytomous Item Response Theory Models to Multiple-Choice Tests.
Drasgow, Fritz; And Others
Applied Psychological Measurement, v19 n2 p143-65 Jun 1995
This study examined how well current software implementations of four polytomous item response theory models fit several multiple-choice tests. The main conclusion is that fitting polytomous item response models to multiple-choice item responses is more complex than fitting the three-parameter logistic model to dichotomously scored responses.
