Stone, Clement A.
Journal of Educational Measurement, v37 n1 p58-75 Spr 2000
Describes a goodness-of-fit statistic that considers the imprecision with which ability is estimated and involves constructing item fit tables based on each examinee's posterior distribution of ability, given the likelihood of the response pattern and an assumed marginal ability distribution. Also describes a Monte Carlo resampling procedure to assess the significance of the fit statistic. (SLD)
