Abstract:

Several special cases of the general Rasch model, varying in complexity, were investigated to determine whether they could successfully model realistic multidimensional item response data. Also investigated was whether the parameters of the model could be readily interpreted. Of the formulations of the model investigated, all but two were found to be incapable of modeling realistic multidimensional item response data. One of the remaining formulations of the model was found to have limited applications. The version of the model found to be most useful is an extension of the two-parameter logistic model. Author
