Foundations for the Mathematical Notion of Information in Item Response Theory and Robust Ability Estimation.
Jones, Douglas H.
A mathematical setting based on a statistical sampling probability mechanism is described. In this setting, a mathematical meaning is given for the information function; and it becomes possible to study the relative merits of various ability-estimating procedures. The maximum likelihood estimation procedure under the one-, two-, three-parameter logistic response model and new procedures that are suggested by resistant/robust theory are compared. (Author/PN)
