Title:
New Regression Model: Modal Regression


Abstract:

Built on the ideas of mean and quantile, mean regression and quantile
regression are extensively investigated and popularly used to model the
relationship between a dependent variable Y and covariates x. However, the
research about the regression model built on the mode is rather limited.
In this talk, we propose a new regression tool, named Modal Regression,
that aims to find the most probable conditional value (mode) of a
dependent variable Y given covariates x rather than the mean that is used
by the traditional mean regression. The modal regression can reveal new
interesting data structure that is possibly missed by the conditional mean
or quantiles. In addition, modal regression is resistant to outliers and
heavy-tailed data, and can provide shorter prediction intervals when the
data are skewed. Furthermore, unlike traditional mean regression, the
modal regression can be directly applied to the truncated data. Modal
regression could be a potentially very useful regression tool that can
complement the traditional mean and quantile regressions.


------------------------------------
Sponsored by the UCR Data Science Center, the purpose of the Data Science
Seminars is to foster collaborations between "core" Data Science faculty
(from CSE/ECE/Stat Departments) and faculty/visitors from other sciences
that face Data Science problems in their research. These informal
gatherings are open to interested faculty and graduate students. Each
meeting will start with a talk describing research problems and then a
discussion will follow for questions, open problems, ideas for possible
collaborations etc.

lab that may be interested. Moreover, if you are interested in giving a
