Purple Unicorns, True Models, and Other Things I've Never Seen
Edwards, Michael C.
Measurement: Interdisciplinary Research and Perspectives, v11 n3 p107-111 2013
This author has had the privilege of knowing Professor Maydeu-Olivares for almost a decade and although their paths cross only occasionally, such instances were always enjoyable and enlightening. Edwards states that Maydeu-Olivares' target article for this issue, ("Goodness-of-Fit Assessment of Item Response Theory Models") provides both an excellent overview of the current state-of-the-art in assessment of fit in item response theory (IRT) as well as lots of food for thought about the task of assessing model fit more generally. Edwards' goal in this commentary is to continue the conversation Professor Maydeu-Olivares has already begun. Edwards' commentary is split into three sections: (1) a general reaction to the state of assessment as portrayed by Professor Maydeu-Olivares; (2) a reaction to some conceptual confusion he sees in the literature in general; and (3) a collection of more minor but, important points. The focus article (mentioned above) was informative, but perhaps more importantly, it made Edwards think; question some of his underlying assumptions about the endeavor of assessing model fit; and wonder what impact this will all have on how IRT is conducted and reported.
