The Influence of Dimensionality on Estimation in the Partial Credit Model.
De Ayala, R. J.
Educational and Psychological Measurement, v55 n3 p407-22 Jun 1995
The effect of multidimensionality on partial credit model parameter estimation was studied with noncompensatory and compensatory data. Analysis results, consisting of root mean square error bias, Pearson product-moment corrections, standardized root mean squared differences, standardized differences between means, and descriptive statistics support the use of the Rasch family of models.
