InDisc is an R Package that implements procedures for estimating and fitting unidimensional Item Response Theory (IRT) Dual Models (DMs). DMs are intended for personality and attitude measures and are, essentially, extended standard IRT models with an extra person parameter that models the discriminating power of the individual. The package consists of a main function, which calls subfunctions for fitting binary, graded, and continuous responses. The program, a detailed user's guide, and an empirical example are available at no cost to the interested practitioner.
InDisc是一个R软件包，它实现了用于估计和拟合单维项目反应理论（IRT）对偶模型（DMs）的程序。对偶模型适用于人格和态度测量，本质上是扩展的标准IRT模型，带有一个额外的个体参数，用于对个体的辨别力进行建模。该软件包包含一个主函数，该主函数调用用于拟合二元、分级和连续反应的子函数。感兴趣的从业者可以免费获得该程序、详细的用户指南和一个实证示例。
