Estimation of the Operating Characteristics of Item Response Categories III: The Normal Approach Method and the Pearson System Method.

Abstract

Two new variations of the Conditional P.D.F. Method for estimating the operating characteristics of item response categories are introduced. They are called the Normal Approach Method and the Pearson System Method. Just like the Two-Parameter Beta Method, these two methods are characterized by such facts that: (1) no prior mathematical models are assumed for the operating characteristics; (2) a relatively small number of examinees is used in the whole process; (3) the joint distribution of the latent trait theta and its maximum likelihood estimate is fully utilized, and (4) the method of moments is effectively applied.
