Jackknifing Techniques for Evaluation of Equating Accuracy. Research Report. ETS RR-09-39
Haberman, Shelby J.; Lee, Yi-Hsuan; Qian, Jiahe
ETS Research Report Series, Dec 2009
Grouped jackknifing may be used to evaluate the stability of equating procedures with respect to sampling error and with respect to changes in anchor selection. Properties of grouped jackknifing are reviewed for simple-random and stratified sampling, and its use is described for comparisons of anchor sets. Application is made to examples of item response theory (IRT) true-score equating in which two-parameter logistic and general partial credit models are employed.
