The Meaning of Goodness-of-Fit Tests: Commentary on "Goodness-of-Fit Assessment of Item Response Theory Models"
Measurement: Interdisciplinary Research and Perspectives, v11 n3 p123-126 2013
In this commentary, David Thissen states that "Goodness-of-fit assessment for IRT models is maturing; it has come a long way from zero." Thissen then references prior works on "goodness of fit" in the index of Lord and Novick's (1968) classic text; Yen (1984); Drasgow, Levine, Tsien, Williams, and Mead (1995); Chen and Thissen (1997); and Reiser (1996). Thissen adds that Maydeu-Olivares and his colleagues have made the most significant contributions to goodness-of-fit testing for IRT models for the past decade, thus, Maydeu-Olivares is uniquely qualified to write the focus article, which consists largely of a clear exposition of unassailable facts. This commentary takes a step back, considering the usefulness and meaning of overall goodness of fit tests for IRT.
