The Bayesian analysis based on the partial likelihood for Cox's proportional hazards model is frequently used because of its simplicity. The Bayesian partial likelihood approach is often justified by showing that it approximates the full Bayesian posterior of the regression coefficients with a diffuse prior on the baseline hazard function. This, however, may not be appropriate when ties exist among uncensored observations. In that case, the full Bayesian and Bayesian partial likelihood posteriors can be much different. In this paper, we propose a new Bayesian partial likelihood approach for many tied observations and justify its use.  相似文献

As clinical social work developed in America it was highly influenced by the concepts and techniques of psychoanalysis and many of its practitioners became interested in seeking psychoanalytic training. More and more psychoanalysts are now coming from a background in clinical social work due to the development of a network of interdisciplinary training institutes and the opening of the Institutes of the American Psychoanalytic Association to non-medical candidates. This special issue considers how psychoanalysis may be affected as more of its practitioners and contributors come from a background in clinical social work. This introduction reviews the history of the development of clinical social work and outlines the issues related to “lay analysis” in this country.

Local influence is a well-known method for identifying the influential observations in a dataset and commonly needed in a statistical analysis. In this paper, we study the local influence on the parameters of interest in the seemingly unrelated regression model with ridge estimation, when there exists collinearity among the explanatory variables. We examine two types of perturbation schemes to identify influential observations: the perturbation of variance and the perturbation of individual explanatory variables. Finally, the efficacy of our proposed method is illustrated by analyzing [13 A. Munnell, Why has productivity declined? Productivity and public investment, New Engl. Econ. Rev. (1990), pp. 322. [Google Scholar]] productivity dataset.  相似文献

This paper explores the current status of professionalization of communication management practice which emerged from a content analysis of 360 responses to questions exploring the nature of practitioner identity (or dis-identity) with communication management. The results revealed that positive identification arose from an ability to influence, emulate the professional values of peers, and cohesion with the wider practitioner community. Conversely, dis-identification arose from the poor performance of colleagues, advice not being taken, and media ‘spin’.  相似文献

Concerns about decreasing response rates have led to many nonresponse studies. Unfortunately, usually only a limited amount of data is available on nonrespondents. Linking administrative data makes information available on all the sampled units including nonrespondents. Statistics Netherlands has constructed a database in which several administrative records and several surveys are connected. In this explorative study we use this dataset to look for homogenous groups of respondents and nonrespondents in survey research using latent class cluster analysis. Latent class techniques can provide insight into the problem of selective nonresponse and currently under-represented societal groups. We identify four different latent classes in a recent Dutch survey and replicate the findings for the same survey conducted 4 years later. Two of the types of sampled units have above-average response rates and the other two have below-average response rates. We also evaluate various latent class models with other response outcomes to gain insight into the contact and cooperation process.  相似文献

"管他"是一个至今未被收入虚词词典的连词性成分。在现代汉语中,"管他"虽然没有词汇化为一个词,但它是一个经过句法上的并入操作而实现的韵律词,比"管"更有资格充当连词性成分。"管他"语法化为连词性成分首先是语义条件,即"管"由行为动词演变为心理动词、代词"他"的意义虚化,其次是语音条件,即现代汉语双音节的自然音步模式。此外,"管他"语法化为连词的直接语境是反问句,相关语境是否定句。  相似文献
