Probability Generating Function Based Jeffrey's Divergence for Statistical Inference

Statistical inference procedures based on transforms such as characteristic function and probability generating function have been examined by many researchers because they are much simpler than probability density functions. Here, a probability generating function based Jeffrey's divergence measure is proposed for parameter estimation and goodness-of-fit test. Being a member of the M-estimators, the proposed estimator is consistent. Also, the proposed goodness-of-fit test has good statistical power. The proposed divergence measure shows improved performance over existing probability generating function based measures. Real data examples are given to illustrate the proposed parameter estimation method and goodness-of-fit test.

Open Dialogue: Frequently Asked Questions

Open Dialogue is an approach to working with people and their families experiencing psychosocial distress. Interest in Open Dialogue in Australia has been growing recently, raising questions about its adaption and implementation to local contexts. This article is an attempt to answer some of the frequently asked questions we have encountered in training and discussions about Open Dialogue. We attempt to provide responses to questions of how Open Dialogue is different to what is done already, how it fits with current approaches, how you know if you are doing it, whether it is passive or just about doing reflections, issues about including the social network, and concerns about the evidence base. This article aims to present a variety of viewpoints in relation to these questions and to hopefully further discussions on how Open Dialogue can be implemented and adapted to Australian health care and social care contexts.     

Data-dependent probability matching priors of the second order

In this paper, we consider the preliminary test approach for the estimation of the regression parameter in a multiple regression model under a multicollinearity situation. The preliminary test two-parameter estimators based on the Wald (W), likelihood ratio, and Lagrangian multiplier tests are given, when it is suspected that the regression parameter may be restricted to a subspace and the regression error is distributed with multivariate Student's t distribution. The bias and mean square error of the proposed estimators are derived and compared. The conditions of superiority of the proposed estimators are obtained. Finally, we conclude that the optimum choice of the level of significance becomes the traditional choice by using the Wald test.     

Probability matching priors for two-sided tolerance intervals in balanced one-way and two-way nested random effects models

We consider two-sided Bayesian tolerance intervals, with approximate frequentist validity, for a future observation in balanced one-way and two-way nested random effects models. Probability matching conditions, specific to this problem, are derived in either case via a technique that involves inversion of approximate posterior characteristic functions. In addition to yielding probability matching priors for the present problem, these conditions are useful in evaluating certain other priors that have received attention in the literature.     

Establishing self and meaning in low back pain narratives

Pain narratives encounter the problem of verbalising private and internalised experiences. Words appear to fall short of giving meaning to the feelings and impact of pain. In this paper we report on how people describe their low back pain and the way in which they claim to present this to clinicians. In the research interviews they need to establish themselves as believable narrators and provide accounts of how they legitimise their pain in clinical encounters. As a result, the interviews provide complex and layered narratives of pain and its representation.     

论宗教对我国西北边疆安全的双重影响

宗教对国家安全和社会政治稳定所产生的影响主要表现在其所特有的功能上。一方面,当宗教与社会政治体系相一致时,它就能促使其社会成员共同意志、共同信念的形成,对国家安全和社会政治稳定起到明显的促进作用;另一方面,宗教作为一种文化现象,还是科学与非科学、理性与非理性、道德与非道德相对而言的复杂统一体,因此具有滞后性、敏感性、触发性,当它成为引发社会不稳定的"互动源"和"感染源"时,会对国家安全和社会政治稳定产生负面影响。
