Investigation of IRT-Based Equating Methods in the Presence of Outlier Common Items (2008, methodology): “Computer simulations have been employed in many studies to investigate IRT-based equating methods (e.g., Baker, 1996; Bolt, 1999; Cohen & Kim, 1998; Hanson & Beguin, 2002; Wang, Hanson, & Harris, 2000).”
A Comparison of the Frequency Estimation and Chained Equipercentile Methods Under the Common-Item Nonequivalent Groups Design (2008, methodology): “Following a procedure used by Hanson and Béguin (2002), the item parameters for the four test forms were put on a common scale.”
Robustness to Format Effects of IRT Linking Methods for Mixed-Format Tests (2006, background): “This finding has also been reported in previous studies that deal with single-format tests (Baker & Al-Karni, 1991; Hanson & Béguin, 2002; S.-H. Kim & Cohen, 1992; Ogasawara, 2001).”
The DIF-Free-Then-DIF Strategy for the Assessment of Differential Item Functioning (2012, methodology): “The a and b parameters of the 40 items for the reference group were adopted from Hanson and Beguin (2002), in which the a parameters were between 0.”
