A Comparison of Robust Linking Methods with Multiple Outlying Common Items

• In Event: Scaling, Linking, and Equating

Abstract

Common items (CIs) play a crucial role in scale linking. When existing outlying CIs, retaining them is recommended to maintain content balance and psychometric characteristics rather than removing them. Robust linking methods, reducing the influence of outlying CIs have been suggested, and those are compared through simulation under various conditions.
