近日,潘璠在其《统计科研正逢其时》一文中说:解决统计实践中正在面临的诸多现实问题,开展科研,破解难题,也正是统计科研的生命力所在。读张仲梁《碎片语境下的统计话语权》(《统计研究》2011第9期,以下简称《话语权》)。同感潘璠。 相似文献

Several political commentary journals are among America's best-known print journals. This article analyzes their online editions to see how well they are making use of such elements as interactive discussion, rapid publication, and ancillary links. Political discourse has been a mainstay of journal publishing since Addison and Steele started the Spectator, the first periodical for a popular audience, in London in 1711. Some of the oldest American journals are those featuring political commentary. Such journals proliferated in the nineteenth and twentieth centuries when some of their writers and editors like William F. Buckley Jr. grew to be considered powerful political forces in their own right. 相似文献

This article identifies four problems with the present federal statistical system for economics: (1) lack of comparability of data series; (2) fragmentation and poor data quality; (3) nonoptimal funding patterns; and (4) susceptibility of the system to politicization. Full centralization of the system appears to be both impractical and undesirable as a solution; however, considerable consolidation in the statistics collection process and a substantial increase in the number and professional quality of personnel devoted to planning, developing, and coordinating the federal statistical system are recommended. 相似文献

We consider the following fragmentation model of the unit interval 𝕀. We start fragmenting 𝕀 into two pieces with uniform random sizes. One of these two subintervals is then chosen at random according to a β-size-biased picking procedure, β ∈ ?. This particular tagged fragment is next broken into two random pieces, one of which is chosen accordingly at random for further splitting; the process is then iterated independently. This model constitutes a recursive β-partitioning procedure where splitting occurs only at one of the two fragments formed in the previous step of fragmentation. We investigate some statistical features of this model. 相似文献

This paper introduces the mixture of left–right truncated normal distributions, from the spreads between bid and ask prices, as a statistical model for handle non-normality of asset price returns. It has been proved that there is only one maximum for the likelihood function of the new model. 相似文献

State fragility is a concept that entered the political discourse in the last decades producing remarkable implications for aid allocation and international policies. The operationalization of this concept has generated a number of composite indices to produce rankings of fragile states. However, the temporal dimension of the driving forces leading to fragility has been rather neglected. This article discusses a statistical procedure that helps to represent the global fragility of a country and the path that a country has followed or will follow in the future when possibly entering into (or escaping from) a fragility condition. Specifically, multiple factor analysis is applied to depict vulnerable and weak countries, and to identify the fundamental forces that determine their overall fragility. Moreover, the trajectories of countries along the years are estimated using partial factor scores. Finally, the path of each country is predicted by means of parsimonious regression models, based on a reduced set of explanatory variables, and according to scenarios elaborated from available international outlooks. 相似文献

影响统计数据质量的因素是多方面的。提高统计数据质量不仅要改进统计的方法技术,还需要建设优良的统计社会环境,为统计提供良好的条件,所以应当重视“统计生态环境建设”的问题。“统计生态环境建设”包括有利于确保数据质量的思想观念环境、政府统计的体制环境、包含数据真实性的社会信用体系以及保障统计数据质量的法制环境。 相似文献
