根据项目反应理论，差异项目功能 (DIF) 的检测最常在两组考生之间进行。然而，有时确定 DIF 是否存在于两个以上的组中也很重要。在本文中，我们提出了一种检测多组 DIF 的方法。该方法与洛德卡方密切相关，用于比较两组中估计的项目参数向量。提供了使用真实数据的示例。
Detection of differential item functioning (DIF) is most often done between two groups of examinees under item response theory. It is sometimes important, however, to determine whether DIF is present in more than two groups. In this article we present a method for detection of DIF in multiple groups. The method is closely related to Lord's chi-square for comparing vectors of item parameters estimated in two groups. An example using real data is provided.
