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包,可实现估计和拟合一维项目响应理论(IRT)对偶模型(DM)的过程。DM旨在用于性格和态度测量,并且本质上是具有额外人员参数的扩展标准IRT模型,该参数对个人的识别能力进行建模。该程序包包含一个主要函数,该函数调用子函数来拟合二进制,分级和连续响应。感兴趣的从业人员可以免费获得该程序,详细的用户指南和经验示例。
