题目: TitleVector Generalized Linear Models: A Gaussian Copula Approach

报告人: 宋学坤教授

(加拿大Waterloo大学统计与精算科学系)

时间: 2006年4月7日(周五)上午10点

地点: 理科楼207

内容简介: A multivariate extension to the classic generalized linearmodels using the approach of the Gaussian copula. This extensionfurnishes a unified framework of analyzing multi-dimensional non normaldata in the context of regression analysis(The proposed models canaccommodate discrete, continuous and mixed vector outcomes arising inmany practical studies, including longitudinal, clustered or spatial data.With the availability of joint probability distributions, we develop asimultaneous maximum likelihood inference in the class of models, wherea Gauss-Newton type algorithm is implemented to obtain numerical resultsfor the parameter estimation. I will illustrate vector logistic (or probit)models for multivariate binary outcomes, vector log-linear models formultivariate count outcomes, and a vector GLM for normal and binary mixedoutcomes. Comparisons to the GEEs (Generalized Estimating Equations) approachwill be discussed in detail through both simulation and data analysis examples.

明天开运动会哦 讲座还继续吗?

继续，没有办法，专家日程安排定了的，今天下午7点到重庆，后天上午离开，就明天在重庆

好可惜啊

本来这讲座是和我们专业有关的

但是由于运动会的关系

很有可能去不成了

遗憾啊

那位同学拷贝了今天宋教授讲课的课件,我拷贝的打不开!

拷了的请给我传一份或者传到SCI上

谢谢!
