Tests of serial independence based on Kendall's process

The authors propose new rank statistics for testing the white noise hypothesis in a time series. These statistics are Cramér‐von Mises and Kolmogorov‐Smirnov functionals of an empirical distribution function whose mean is related to a serial version of Kendall's tau through a linear transform. The authors determine the asymptotic behaviour of the underlying serial process and the large‐sample distribution of the proposed statistics under the null hypothesis of white noise. They also present simulation results showing the power of their tests.

从文献著录看“七体”的演变

“七”在中国古代文体史上立为一体，由来已久，其文体地位在古代史书、类书、书目等文献中都有明确的著录；随着创作的发展变化，七体在后世总集中的归类及收录范围有所变化，据此可以更深入地探讨七体的文体属性和发展演变，也可看出文体分类及演变过程中的复杂性和多样性。     

Estimation for hidden Markov random fields

A finite state Markov random field is noisily observed via a second finite state process. The parameters of the model are estimated, as well as the most likely signal given the observations.

高斯与观测误差分布的发现

在数理统计的发展史上,最重要的事件也许就是观测误差分布的发现。统计学家们在寻找观测误差分布的过程中,创造了许多有用的统计理论和方法,不过观测误差分布发现的优先权最终属于伟大的德国科学家高斯。文章主要介绍了高斯发现观测误差分布的思考过程,并期望读者能从高斯天才的思想中获得有益的启迪。     

Ticking Boxes and Changing the Social World: Data Collection and the New UK General Practice Contract

The new General Medical Services contract was introduced into general practice in the UK in 2004, and it links pay to performance far more than in the past. As a result, accurate data collection about patients and the care that they receive is now not only important for good patient care but also to prove that targets are being met. The use of electronic records and information technology has thus become much more sophisticated. This article reports the results from an ethnographic study of the early stages of the new contract in two general practices. As expected, electronic data collection had increased in importance in both practices, with consequences both for clinician–patient interactions and for the structures and processes in the practices, as uniform data collection instruments are put in place that privilege ‘hard’ biomedical data that can be easily coded above ‘softer’, more patient-centred information. Roles and responsibilities had been changed to reflect the needs of the new systems, and new software applications allowed increased surveillance of both doctors’ and nurses’ performance; both of these had an impact on patterns of authority in our study practices. Furthermore, the structural changes that were found acted to embed the new ways of working, ensuring their reproduction in the future. In spite of these effects, we found little opposition to or critical reflection on the changes, and the doctors in our study continued to view their improved computer systems as neutral recording devices. The implication of these findings is discussed.     

日本现存中国大陆缺、残明代地方志考录

明代对纂修地方志书极为重视,遍及各州郡县,所修方志数量极为可观,但散佚很多。通过对日本现存明代地方志与中国大陆地区相比较,发现有许多是中国大陆缺藏或残存的,因此显得弥足珍贵,而且对目前所见有关地方志目录有所补正。     

Bayesian estimation of P (Y<X) from Burr-type X model containing spurious observations

We consider the problem of estimating R=P(Y<X) when X and Y are independent Burr-type X random variables. We assume that the sample from each population contains one spurious observation. Bayes estimates are derived for exchangeable and identifiable cases. Monte Carlo simulation is carried out to compare the bias and the expected loss of R.
