Psychometric Data Analysis: A Size/fit Trade-off Evaluation Procedure for Knowledge Structures

A crucial problem in knowledge space theory, a modern psy chological test is the derivation of realistic structure representing organization an information domain and examinee population under reference. Often, one left with selecting among candidate competing structures. This article proposes measure for selection It derived within operational framework (prediction paradigm), partly based on unitary method proportional reduction predictive error as advocated by authors Guttman, Goodman, Kruskal. In particular, this designed to trade off (descriptive) fit size structure, which high interest theory. The proposed approach compared Correlational Agreement Coef ficient, has been recently discussed surmise relations. Their performances measures are simulation study using fundamental basic local independence model theory
