Confidence intervals,significance values,maximum likelihood estimates,etc. sharpened into Occam’s razors

Abstract

Confidence sets, p values, maximum likelihood estimates, and other results of non-Bayesian statistical methods may be adjusted to favor sampling distributions that are simple compared to others in the parametric family. The adjustments are derived from a prior likelihood function previously used to adjust posterior distributions.     

英汉互译中的音义对应及其可译性限度

声音、节奏等具有伴随意义,有时是对语言本身意义的补充.在翻译时力求音义对应是实现等效翻译的一种重要手段.当然,英汉语音在结构、功能和表达方式上的差异也使音义对应有一定的限度.     

纪昀的西域谪戍生涯及《阅微草堂笔记》反映西域风土人情的特点

乾隆三十三年 ,纪昀因为“漏言”被谪贬至西域乌鲁木齐。与古代其他谪贬文人所不同的是 ,他并未完全沉浸于穷愁怨艾的情绪中 ,而是以积极乐观的人生态度面对现实。他的《乌鲁木齐杂诗》及《阅微草堂笔记》多方面地展示了西域的风土人情。但两者在内容及视角上有所不同 ,《乌鲁木齐杂诗》以丰富见长 ,但多粉饰之意 ;《阅微草堂笔记》以深刻取胜 ,真实而颇见其洞察力

Holistic trajectories: a study of combined employment, housing and family careers by using multiple-sequence analysis

Summary.  Social science applications of sequence analysis have thus far involved the development of a typology on the basis of an analysis of one or two variables which have had a relatively low number of different states. There is a yet unexplored potential for sequence analysis to be applied to a greater number of variables and thereby a much larger state space. The development of a typology of employment experiences, for example, without reference to data on changes in housing, marital and family status is arguably inadequate. The paper demonstrates the use of sequence analysis in the examination of multivariable combinations of status as they change over time and shows that this method can provide insights that are difficult to achieve through other analytic methods. The data that are examined here provide support to intuitive understandings of clusters of common experiences which are both life course specific and related to socio-economic factors. Housing tenure is found to be of key importance in understanding the holistic trajectories that are examined. This suggests that life course trajectories are sharply differentiated by experience of social housing.

论沈约的山水诗

沈约是齐梁之际的著名诗人。他的山水诗集中创作于东阳外任期间。其山水诗作景物描写细致生动,而诗中的情与景却呈现为不相交融的割裂状态,并带有较多的述行意味。沈约山水诗的这种特征与当时的文学风气虽然相左,却与前代的谢灵运有类似之处。而导致这种相左与相似的主要原因便在于个人的遭遇与心态。

Bayesian locally optimal design of knockout tournaments

The elimination or knockout format is one of the most common designs for pairing competitors in tournaments and leagues. In each round of a knockout tournament, the losers are eliminated while the winners advance to the next round. Typically, the goal of such a design is to identify the overall best player. Using a common probability model for expressing relative player strengths, we develop an adaptive approach to pairing players each round in which the probability that the best player advances to the next round is maximized. We evaluate our method using simulated game outcomes under several data-generating mechanisms, and compare it to random pairings, to the standard knockout format, and to two variants of the standard format.     

降低线性调频脉冲压缩信号旁瓣的方法

讨论线性调频脉冲压缩信号距离旁瓣的抑制。研究如何降低小时带积线性调频信号距离旁瓣电平问题,针对该信号频谱矩形特性差,提出了采用频谱修正方法来提高脉冲压缩信号的主副比。该方法具有全数字式处理特点,适宜使用IMS A100器件实现脉冲压缩处理。计算机模拟结果表明,无论是小时带积还是大时带积的线性调频信号,经谱修正后,脉冲压缩信号的主副比均舍得到提高。
