SIMEX-Based and Analytical Bias Corrections in Stocking–Lord Linking
AnalyticsStocking–Lord (SL) linking is a popular linking method for group comparisons based on dichotomous item responses. This article proposes a bias correction technique based on the simulation extrapolation (SIMEX) method for SL linking in the 2PL model in ...

Bias-Corrected Root Mean Square Deviation Estimators
FoundationsThe root mean square deviation (RMSD) is a widely used item fit statistic in item response models. However, the sample RMSD is known to exhibit positive bias in small samples. To address this, seven alternative bias-corrected RMSD estimators are proposed

Parameter Estimation Accuracy of the Effort-Moderated IRT Model Under Multiple Assumption Violations
, 2020 As low-stakes testing contexts increase, low test-taking effort may serve as a serious validity threat. One common solution to this problem is to identify noneffortful responses and treat them as missing during parameter estimation via the Effort ...
