We deal with two-way contingency tables having ordered column categories. We use a row effects model wherein each interaction term is assumed to have a multiplicative form involving a row effect parameter and a fixed column score. We propose a methodology to cluster row effects in order to simplify the interaction structure and to enhance the interpretation of the model. Our method uses a product partition model with a suitable specification of the cohesion function, so that we can carry out our analysis on a collection of models of varying dimensions using a straightforward MCMC sampler. The methodology is illustrated with reference to simulated and real data sets. 相似文献

In this paper we consider spatial regression models for count data. We examine not only the Poisson distribution but also the generalized Poisson capable of modeling over-dispersion, the negative Binomial as well as the zero-inflated Poisson distribution which allows for excess zeros as possible response distribution. We add random spatial effects for modeling spatial dependency and develop and implement MCMC algorithms in $R$ for Bayesian estimation. The corresponding R library ‘spatcounts’ is available on CRAN. In an application the presented models are used to analyze the number of benefits received per patient in a German private health insurance company. Since the deviance information criterion is only appropriate for exponential family models, we use in addition the Vuong and Clarke test with a Schwarz correction to compare possibly non nested models. We illustrate how they can be used in a Bayesian context. 相似文献

The article analyses experimental “solidarity games” with two benefactors and one beneficiary. Depending on their motive for
giving—e.g., warm glow, altruism, or guilt—the benefactors’ response functions are either constant, decreasing, or increasing.
If motives interact, or if envy is a concern, then more complex (unimodal) shapes may emerge. Controlling for random utility
perturbations, we determine which and how many motives affect individual decision making. The main findings are that the motives
of about 75% of the subjects can be identified fairly sharply, that all of the motives discussed in the literature co-exist
in the population, and that for any given individual no more than two motives (out of six motives considered overall) are
identified. We conclude that a unifying motive for solidarity cannot be derived even when we allow for individually heterogeneous
parameterization: different subjects give for different reasons and all existing social preference theories are partially
correct. 相似文献

We study an autoregressive time series model with a possible change in the regression parameters. Approximations to the critical values for change-point tests are obtained through various bootstrapping methods. Theoretical results show that the bootstrapping procedures have the same limiting behavior as their asymptotic counterparts discussed in Hušková et al. [2007. On the detection of changes in autoregressive time series, I. Asymptotics. J. Statist. Plann. Inference 137, 1243–1259]. In fact, a small simulation study illustrates that the bootstrap tests behave better than the original asymptotic tests if performance is measured by the α- and β-errors, respectively. 相似文献

This paper explores black African childrens experiencesof the child protection system in the UK. The central focusof the paper is a review of the available literature on thesocial circumstances and environmental influences affectingmany black African families involved in the child protectionsystem; specific parenting practices and care-giving environments;and their experiences of social work and other professionalinterventions aimed at safeguarding and promoting the needsof African children. This paper examines these themes to elucidatethe factors that contribute to the provision of effective, culturallycompetent interventions with black African children at riskof significant harm. It suggests that there are a number oftensions inherent for professionals in working with culturallydiverse African families such as reconciling different beliefsand behaviours concerning child-rearing practices; affirmingthe parenting practices of these families in the engagementprocess; adopting a strengths-based orientation whilst at thesame time safeguarding and promoting the welfare of vulnerablechildren. The paper concludes with a discussion of the implicationsfor practice. 相似文献

Summary We propose a new class of prior distributions for the analysis of discrete graphical models. Such a class, obtained following
a conditional approach, generalizes the hyper Dirichlet distributions of Dawid and Lauritzen (1993), since it can be extended
to non decomposable graphical models. The two classes are compared in terms of model selection, with an application to a medical
data-set illustrating the performance of the two resulting procedures. The proposed class turns out to select simpler, more
par-simonious structures. 相似文献

Through a glass darkly: Chronic illness in the therapist 总被引:1,自引:1,他引:0
This paper is about doing psychotherapy while suffering from a chronic illness. The purpose is to describe the manner in which ongoing irreversible pain integrates itself into the life of any human being, but specifically that of the therapist. The process of weaving the experience into the life narrative and in turn the therapeutic narrative is explored. 相似文献

We use a large Italian employer-employee matched dataset to study how motherhood affects women’s working career in terms of labor force participation and wages. We confirm that the probability of exiting employment significantly increases for mothers of pre-school children; however, this is mitigated by higher job quality, human capital endowment and childcare accessibility. Most importantly, the availability of part-time jobs reduces their probability of moving out of the labor force. Women not leaving employment after becoming mothers experience lower wages than women with no pre-school child, and there are no signs of this gap closing 5 years after childbirth. Contrary to previous literature, the wage gap penalty emerges only among women working full-time, thanks to the high protection accorded to part-time jobs in Italy. 相似文献

Research has documented that the transition from Temporary Assistance for Needy Families (TANF) can be a critical period that results in elevated stress for families. The present study utilizes administrative data to examine the experiences of families exiting TANF and factors that influence subsequent child maltreatment, with particular focus on type of exit from TANF and earned income from employment. Families in the study are 18,023 female-headed households from an urban Ohio county who exited TANF between January 1, 1999 and December 31, 2002. Of these families, 894 (4.96%) experienced an indicated or substantiated finding of maltreatment within two years of their initial exit from TANF. Cox proportional hazard models identified several significant predictors of child maltreatment. Findings indicate that families with an involuntary exit from TANF were at increased risk of a substantiated or indicated finding of maltreatment while families with higher earnings from employment were at a reduced risk of maltreatment. These findings suggest that policy makers and program staff may need to reconsider their approach with these families to ensure the well-being of children. Strategies to improve employment opportunities and limit involuntary exits are discussed. 相似文献
