Model-Free CUSUM Methods for Person Fit
Armstrong, Ronald D.; Shi, Min
Journal of Educational Measurement, v46 n4 p408-428 Win 2009
This article demonstrates the use of a new class of model-free cumulative sum (CUSUM) statistics to detect person fit given the responses to a linear test. The fundamental statistic being accumulated is the likelihood ratio of two probabilities. The detection performance of this CUSUM scheme is compared to other model-free person-fit statistics found in the literature as well as an adaptation of another CUSUM approach. The study used both simulated responses and real response data from a large-scale standardized admission test.
