Empirical Power and Type I Error Rates for an IRT Fit Statistic That Considers the Precision of Ability Estimates.
Stone, Clement A.
Educational and Psychological Measurement, v63 n4 p566-83 Aug 2003
Developed and investigated a goodness-of-fit statistic that considers the uncertainty with which ability is estimated and a resampling-based hypothesis testing procedure. Simulation study results indicate that the procedure should be useful for evaluating goodness-of-fit item response theory models for most testing applications when uncertainty in ability estimation is an issue.
