Test Theory Without an Answer Key.

Batchelder, William H.; Romney, A. Kimball

Psychometrika, v53 n1 p71-92 Mar 1988

A general model is presented for homogeneous, dichotomous items when the answer key is unknown. The model is related to the two-class latent structure model with the roles of respondents and items interchanged. Iterative maximum likelihood estimates of parameters and Monte Carlo assessment of estimation methods are described. (TJH)
