On Christensen's conjecture

In this paper we give solution to a conjecture appearing in Christensen (1997, p. 360) in relation to the definitions of standardized residuals in loglinear models. Work done when he was visiting as the Distinguished Lukacs Professor on leave from the Complutense University of Madrid. An erratum to this article is available at .     

A multivariate version of Gini's rank association coefficient

In this paper, we introduce a multivariate generalization of the population version of Gini's rank association coefficient, giving a response to this open question posed in [4]. We also study some properties of this version, present the corresponding results for the sample statistic, and provide several examples.     

Multivariate inverse Gaussian distribution as a limit of multivariate waiting time distributions

Multivariate inverse Gaussian distribution proposed by Minami [2003. A multivariate extension of inverse Gaussian distribution derived from inverse relationship. Commun. Statist. Theory Methods 32(12), 2285–2304] was derived through multivariate inverse relationship with multivariate Gaussian distributions and characterized as the distribution of the location at a certain stopping time of a multivariate Brownian motion. In this paper, we show that the multivariate inverse Gaussian distribution is also a limiting distribution of multivariate Lagrange distributions, which is a family of waiting time distributions, under certain conditions.     

“村村通”广电建设中存在的问题与对策研究

国家对基层广电事业提出了确保"村村通"长期通的新目标,但由于西部基层广电事业自身固有的问题以及在"村村通"建设中产生的新矛盾,完成艰巨任务存在很大困难.而且西部基层广电事业原有的资源条件和经营环境受挤严重,旧的发展方式力不从心,困局渐显.政府主导、行业直管、整合资源、纵深开发是西部基层广电事业改革发展,建立"村村通"长效机制的关键性策略.
