Nonparametric Likelihood and Its Applications

Show Abstract

Nonparametric likelihood is one of the important topics in statistics. In this talk, we will introduce the basic ideas for nonparametric likelihood and present our latest research achievements. For example, we generalize the empirical likelihood to the empirical Lq likelihood and Empirical power divergent likelihood. The former is usually used to the estimating theory, the latter is usually used to the goodness-of-fit. This talk will focus on the goodness-of-fit. In addition, the talk will discuss the adjusted empirical (Euclidean) likelihood and its applications, the nonparametric likelihood for the complex data such as the rounded data, dependent data, high-dimensional data, and so on.
