dcminfo: Information Matrix for Diagnostic Classification Models
软件包网址  https://cran.r-project.org/web/packages/dcminfo/index.html


A set of asymptotic methods that can be used to directly estimate the expected (Fisher) information matrix by Liu, Tian, and Xin (2016) <doi:10.3102/1076998615621293> in diagnostic classification models or cognitive diagnostic models are provided when marginal maximum likelihood estimation is used. For these methods, both the item and structural model parameters are considered simultaneously. Specifically, the observed information matrix, the empirical cross-product information matrix and the sandwich-type co-variance matrix that can be used to estimate the asymptotic co-variance matrix (or the model parameter standard errors) within the context of diagnostic classification models are provided.

这是我跟北京师范大学辛涛教授合作开发的一个用于估计诊断分类模型或者是认知诊断模型参数估计值标准误（信息矩阵）的一个软件包，欢迎大家试用并提出宝贵意见。

厉害

感谢分享，已经安装了，值得好好研究。
