Effects of Differing Item Parameters on Closed-Interval DIF Statistics.
Feinstein, Zachary S.
Applied Psychological Measurement, v19 n2 p131-42 Jun 1995
The closed-interval signed area (CSA) and closed-interval unsigned area (CUA) statistics were studied by Monte Carlo simulation to detect differential item functioning (DIF) when the reference and focal groups had different parameter distributions. Different behaviors of the CSA and CUA as functions of the parameters are discussed. (SLD)
