  EQS 项目反应理论软件包

EQSIRT 1.0-项目反应理论软件包

EQSIRT-一套综合的项目反应理论(IRT,Item Response Theory)软件包-was developed with funding by the U.S. National Cancer Institute through a Small Business Innovation Research (SBIR) grant motivated by NIH’s Patient Reported Outcomes (PROMIS) initiative.

Authors and contributors: EQSIRT was designed by Eric Wu and Peter Bentler, who developed EQS, a popular structural equations modeling program. It was developed with IRT experts Patrick Mair and Steven Reise. Coherent and creative statistical programming was directed by Sam He, and complex interfaces were directed by Guisuo Guo.

EQSIRT有一整套模型构建器来简化可重用IRT命令的构建。类似EQS,程序包括完整的业务数据管理和重用的统计组件来进行初步的数据筛选。EQSIRT是跨平台的,支持 Microsoft Windows, Apple’s Mac OS X (10.6 或更高), 和各种Linux操作系统。

EQSIRT支持下列方法:

·Generalized Partial Credit Model (GPCM)
·Nominal Response Model (NRM)

B.多维模型(Multidimensional Models)
