检查考试成绩的有效性在教育和心理测量中都很重要。个人匹配分析提供了几个统计数据，帮助从业者评估单个项目分数向量是否符合预先指定的项目反应理论模型，或者是否符合一组考生。到目前为止，还缺乏能够轻松获取大多数人适合度统计数据的软件。PerFit R包就是为了填补这个空白而编写的。提供了相对简单的个人匹配统计的理论概述。还给出了一个实用指南，说明如何使用PerFit的主要功能。数值工具和图形工具都用实例进行了描述和说明。其目的是展示如何轻松地将个人匹配统计应用于问卷数据的测试。
Checking the validity of test scores is important in both educational and psychological measurement. Person-fit analysis provides several statistics that help practitioners assessing whether individual item score vectors conform to a prespecified item response theory model or, alternatively, to a group of test takers. Software enabling easy access to most person-fit statistics was lacking up to now. The PerFit R package was written in order to fill in this void. A theoretical overview of relatively simple person-fit statistics is provided. A practical guide showing how the main functions of PerFit can be used is also given. Both numerical and graphical tools are described and illustrated using examples. The goal is to show how person-fit statistics can be easily applied to testing of questionnaire data.
