Logistic Positive Exponent Family of Models: Virtue of Asymmetric Item Characteristic Curves.
Samejima, Fumiko
Psychometrika, v65 n3 p319-35 Sep 2000
Discusses whether the tradition of accepting point-symmetric item characteristic curves is justified by uncovering the inconsistent relationship between the difficulties of items and the order of maximum likelihood estimates of ability. In this context, proposes a family of models, called the logistic positive exponent family, that provides asymmetric item characteristic curves. (Author/SLD)
