摘要
New variants of entropy as measures of item-fit in item response theory are investigated. Monte Carlo simulation(s) examine aberrant conditions of item-level misfit to evaluate relative (compare EMRj, X-2, G(2), S-X-2, and PV-Q(1)) and absolute (Type I error and empirical power) performance. EMRj has utility in discovering misfit.
