Abstract:

A multidimensional extension of the two-parameter logistics latent trait model is presented and some of its characteristics are discussed. In addition, sufficient statistics for the parameters of the model are derived, as is the information function. Finally, the estimation of the parameters of the model using the maximum likelihood estimation technique is also discussed. Author
