磋商·交流·分享·对话--中加统计政策会议扫描

享誉天下的苏州是一座既古老而又充满活力的城市；建设中的苏州工业园区，更是我国改革开放政策所催生的全新发展模式。五月的苏州，春风拂面，细雨绵绵。中加统计政策会议之所以选择在苏州召开，正如国家统计局局长朱之鑫所言，不但合适，而且更有其特殊的意义。因为把现代统计理论引入我国的先行者，著名统计学家——金国宝先生就诞生于苏州。无庸多言，我们的前辈也非常愿意看到一个现代高效率的国家统计体系早日在中国建立。 中加统计政策会议是根据中国国家统计局和加拿大统计局统计信息管理合作项目安排的。加方出席会议的除统计局…

Purposes, methods, philosophies

Peter Armitage has enjoyed a long and distinguished career in biostatistics, and has also given considerable thought to the way in which statistics is taught to non-mathematicians, perhaps because, he says jokingly, he always found maths a bit difficult himself. Now in retirement, he is still communicating statistical ideas in his rôle as Editor of the Encyclopedia of Biostatistics .     

Sample surveys versus experiments,controlled observations,censuses, registers,and local studies

The relative merits and drawbacks of data obtained from the following sources are compared: sample surveys, experimental projects, controlled observations, censuses, registers, and local studies. The importance of representation as the criterion for comparing the value of the data obtained by the various methods is stressed.     

“Who,What, Where,and Why”

The North Carolina Serials Conference was very fortunate to have secured Rachel Frick for its keynote speaker for 2013. The conference was a homecoming for Frick, who is a graduate of the University of North Carolina MSLS program and is currently the Director of the Digital Library Federation Program for the Council on Library and Information Resources (CLIR), a think tank and research organization located in Washington, D.C. The Digital Library Federation (DLF) has been in existence since 1995, its target audiences being digital library practitioners and other interested parties who are on the front-lines of teaching and learning in this specialty. In her address entitled “Who, What, Where, Why, and How,” Frick discussed some of the major initiatives and issues currently occurring within and around librarianship, exploring the effect that these large scale initiatives can, and should, have at the local level. She can be reached at her Twitter feed, @rlfrick.     

Mixtures,embedding, and ancillarity

Ancillary statistics, proposed by Fisher (1925), can be constructed by forming a mixture model (Birnbaum 1962) or can be extracted or derived from a transformation-parameter model (Peisakoff 1951, Fraser 1961) or from the corresponding error-based structural model (Fraser 1968, 1979); these latter models involve an implicit mixture structure. Compound models with ancillaries can also be formed by a cross embedding, discussed from a technical viewpoint in this paper. Of the 25 examples in Buehler (1982), 22 are mixtures or implicit mixtures and 3 correspond to cross embedding. The cross embedding examples exemplify the nonuniqueness difficulties with ancillaries. This paper discusses a simple and two generalized versions of cross embedding but makes no general valuations of these for statistical inference; their role within inference is discussed in Evans, Fraser, and Monette (1984, 1985).     

Censoring,conditionally, and likelihood

The censoring principle is shown to imply a principle similar to the likelihood principle. Further, it is demonstrated that the censoring principle and a weak form of the conditionality principle jointly imply the likelihood principle.
