Corrigendum: A Residual‐Based Differential Item Functioning Detection Framework in Item Response Theory
Hwanggyu Lim, Edison M. Choe, Kyung T. Han · Journal of Educational Measurement · 2023
In the original article, it was written that “Then the MLE scoring and DIF analysis with RDIF statistics were performed using the est_score and rdif functions, respectively, in the R (R Core Team, 2019) package irtplay (p.90).” However, the irtplay package has been removed from the CRAN repository due to intellectual property (IP) violation issues. Instead, a new R package called irtQ (Lim & Wells, 2023) has been released as a successor to irtplay. All IP issues have been resolved in irtQ, ensuring that the package is compliant with industry standards. https://doi.org/10.1111/jedm.12313 We would like to inform that the same functions of est_score and rdif used in the original study are also included in irtQ. Thus, it can be used as a replacement for irtplay. We apologize for any confusion caused by the previous version of the article.
