Multiplicative Adjustment Method for Semiparametric Regression with Mixing Dependent Data

In this article, we extend a semiparametric regression estimator with multiplicative adjustment to time series context. The asymptotic theory and results from a simulation study are discussed. Theoretical results and numerical comparison show that, in the time series case, the semiparametric estimator is better than the traditional local polynomial estimator in a wide neighbourhood around the true regression function.     

Approximating discrete multivariate distributions prom known moments

To approximate the joint distribution of the two-colony stepping-stone model, a finite mixture approach is proposed for constructing discrete multi-variate distributions. This approach generahzes the classic method of linear combinations of independent variables. The stepping-stone model is approximated through matching known moments. Numerical examples from entomology are given. Comparisons are made with the work by Wehrly et al (1993).     

Complete convergence for arrays of rowwise negatively superadditive-dependent random variables and its applications

In this paper, the Rosenthal-type maximal inequalities and Kolmogorov-type exponential inequality for negatively superadditive-dependent (NSD) random variables are presented. By using these inequalities, we study the complete convergence for arrays of rowwise NSD random variables. As applications, the Baum–Katz-type result for arrays of rowwise NSD random variables and the complete consistency for the estimator of nonparametric regression model based on NSD errors are obtained. Our results extend and improve the corresponding ones of Chen et al. [On complete convergence for arrays of rowwise negatively associated random variables. Theory Probab Appl. 2007;52(2):393–397] for arrays of rowwise negatively associated random variables to the case of arrays of rowwise NSD random variables.

Exploring the roles of government involvement and institutional environments in the internationalization of Chinese Internet companies

The interactions between government, institutions, and Internet companies have gained attention in the research on the globalization of China’s Internet. However, few studies have been conducted at the company level, and the knowledge about the roles of government and institutions remains limited. Drawing on institutional theory, this empirical study explored the roles and mechanisms of government involvement and the institutional environment in the internationalization of Chinese Internet companies. The results indicated that government involvement could improve these companies’ degree of international breadth through both state ownership and governmental affiliation. However, the results showed that state ownership had a restraining function on their degree of international depth. In the context of institutional transition in China, these effects could vary according to whether Internet companies operate in good or poor institutional environments. By revealing these relationships, this study contributes to both the theoretical and the empirical understanding of governmental influence and institutional roots in the globalization of China’s Internet.
