Between ICA and SEM

(1)我们已经成功地引入了伊卡方法的验证性质，并开发了一种新的估计方法。这些和相关的结果在意大利的IMPS 2003和2003年的日本行为测量学会年会上发表。(2)本文提出了一种新的非正态结构方程模型框架，并将其应用于统计因果建模问题。这些和相关的结果在横滨的AIC 30和2003年日本行为测量学会年会上发表。(3)我们在加州的IMPS 2004上组织了一个题为“非正态结构方程建模”的特邀论文会议，我本人主持了会议，并做了一个关于“伊卡和SEM之间”的演讲。“（4）2004年10月在中之岛中心举办了伊卡和SEM国际研讨会。我们有80多名参与者。(5)在分析犯罪心理学中的危险因素和保护因素时，我们研究了伊卡中混合矩阵的具体结构。(6)2005年7月，我在荷兰的IMPS2005上发表了一篇题为“SEM和非常态”的特邀论文。(7)利用数据的非正态信息，我们提出了一个解决方案，正常SEM的内在问题，如无法识别的模型，等效模型，饱和模型。(8)我们建议在伊卡和SEM路径分析的基础上确定几个节点（可观察变量）的因果排序。

(1) We have successfully introduced the ICA methodology of confirmatory nature and developed a new estimation method. These and related results were presented in IMPS2003 in Italy and in the annual meeting of the Behaviormetric Society of Japan in 2003.(2) We have proposed a new framework of Nonnormal SEM and applied it to the problem of statistical causal modeling. These and related results were presented in AIC30 in Yokohama and in the annual meeting of the Behaviormetric Society of Japan in 2003.(3) We organized an invited paper session entitled "Nonnormal Structural Equation Modeling" in IMPS2004 in California I myself chaired the session and gave a talk about "Between ICA and SEM."(4) We hosted an international symposium on ICA and SEM at the Nakanoshima Center in October in 2004. We had more than 80 participants.(5) We have studied specific structures on the mixing matrix in ICA in the analysis of risk and protective factors in criminal psychology.(6) In July of 2005, I gave an invited paper entitled "SEM and nonnormality" in the Netherlands in IMPS2005.(7) Using nonnormal information on data, we proposed a solution to the intrinsic problems of normal SEM such as no identifiable models, equivalent models, and saturate models.(8) We suggested to determine causal ordering of several nodes (observable variables) on the basis of ICA and path analysis of SEM.
