Prof. Weixin Yao is a PhD supervisor and Deputy Director of the Department of Statistics at UC Riverside. He focuses on mixed models, nonparametric and semiparametric modeling, robust data analysis, and high-dimensional modeling. He has served as an associate editor of several prestigious journals, including Biometrics, Journal of Computational and Graphical Statistics, Journal of Multivariate Analysis, and The American Statistician. Associate Editor of Journal of Computational and Graphical Statistics, Journal of Multivariate Analysis, and The American Statistician, and Guest Editor of Advances in Data Analysis and Classification. He has published more than 90 papers in SCI journals such as Journal of the American Statistics Association, Journal of the Royal Statistical Society, Ser B, Journal of Economics.

In this presentation, Prof. Weixin Yao introduces a new regression model: multinomial regression. Prof. Yao began his presentation with the applications and advantages of the multinomial regression, then reported his results in the multinomial regression research, and finally introduced some cutting-edge research directions and works. During the question-and-answer session, there were exchanges and discussions with teachers and students from Shanghai Polytechnic University. This lecture broadened the understanding of our students and faculty on the problem of multinomial regression.
