Empirical Likelihood Test for Diagonal Symmetry
Yongli Sang, Xin Dang
Energy distance is a statistical distance between the distributions of random variables, which characterizes the equality of the distributions. Utilizing the energy distance, we de…
Jackknife Empirical Likelihood Approach for K-sample Tests
Yongli Sang, Xin Dang, Yichuan Zhao
The categorical Gini correlation is an alternative measure of dependence between a categorical and numerical variables, which characterizes the independence of the variables. A non…
Depth-based Weighted Jackknife Empirical Likelihood for Non-smooth U-structure Equations
Yongli Sang, Xin Dang, Yichuan Zhao
In many applications, parameters of interest are estimated by solving some non-smooth estimating equations with -statistic structure. Jackknife empirical likelihood (JEL) approa…
Jackknife Empirical Likelihood Methods for Gini Correlations and their Equality Testing
Yongli Sang, Xin Dang, Yichuan Zhao
The Gini correlation plays an important role in measuring dependence of random variables with heavy tailed distributions, whose properties are a mixture of Pearson's and Spearman's…
Kernel entropy estimation for linear processes
Hailing Sang, Yongli Sang, Fangjun Xu
Let be a linear process with bounded probability density function . We study the estimation of the quadratic functional $\int_{\mathbb{R}} f^2(x)\,…
Symmetric Gini Covariance and Correlation
Yongli Sang, Xin Dang, Hailin Sang
Standard Gini covariance and Gini correlation play important roles in measuring the dependence of random variables with heavy tails. However, the asymmetry brings a substantial dif…
