Prediction in linear mixed models 总被引:2,自引:0,他引:2
Sue Welham Brian Cullis Beverley Gogel Arthur Gilmour Robin Thompson 《Australian & New Zealand Journal of Statistics》2004,46(3):325-347
Following estimation of effects from a linear mixed model, it is often useful to form predicted values for certain factor/variate combinations. The process has been well defined for linear models, but the introduction of random effects into the model means that a decision has to be made about the inclusion or exclusion of random model terms from the predictions. This paper discusses the interpretation of predictions formed including or excluding random terms. Four datasets are used to illustrate circumstances where different prediction strategies may be appropriate: in an orthogonal design, an unbalanced nested structure, a model with cubic smoothing spline terms and for kriging after spatial analysis. The examples also show the need for different weighting schemes that recognize nesting and aliasing during prediction, and the necessity of being able to detect inestimable predictions. 相似文献

THE RHETORIC OF SELF-CHANGE: Illness Experience as Narrative 总被引:1,自引:0,他引:1
Arthur W. Frank 《The Sociological quarterly》1993,34(1):39-52
A rhetoric formulating the self as a project for change has developed in our century. Within this rhetoric certain events and experiences are understood as occasions for changing the self; illness is a prime example. In most narratives of illness the author makes some claim for self-change, though these claims vary. The paper identifies several types of claims for self-change and then considers the relation of rhetorical structures to personal experience. 相似文献

1. To equip nurses with the skills necessary for working with disturbed people, nurse educators need to be mindful of not watering down the essential skills necessary for nurses to deal with difficult behaviour in all branches of nursing. 2. These components of a mental health clinical experience should equip the graduate to deal with the pressures of dealing with disturbed people in any environment, as the skills learned generalize to any branch of nursing. 3. Universities can combine with traditional hospital services and community mental health services to provide services to clients with mental illness. An additional benefit is in providing students with an intensive clinical learning experience that reinforces the theory taught in the classroom. 相似文献

Operational researchers, management scientists, and industrial engineers have been asked by Russell Ackoff to become systems scientists, yet he stated that Systems Science is not a science. (TIMS Interfaces, 2 (4), 41). A. C. Fabergé (Science
184, 1330) notes that the original intent of operational researchers was that they be scientists, trained to observe. Hugh J. Miser (Operations Research
22, 903), views operations research as a science, noting that its progress indeed is of a cyclic nature.The present paper delineates explicitly the attributes of simulation methodology. Simulation is shown to be both an art and a science; its methodology, properly used, is founded both on confirmed (validated) observation and scrutinised (verified) art work.The paper delineates the existing procedures by which computer-directed models can be cyclically scrutinised and confirmed and therefore deemed credible. The complexities of the phenomena observed by social scientists are amenable to human understanding by properly applied simulation; the methodology of the scientist of systems (the systemic scientist).
Résumé Russell Ackoff propose à ceux qui s'occupent de recherches opérationnelle, industrielle, et de gestion, d'agir en systems scientists, et pourtant il affirme que systems science n'est pas une science (TIMS Interfaces 2 (4), 41). A. C. Fabergé (Science 184, 1330) remarque, qu'à l'origine, le but de ceux qui s'occupaient de recherche opérationnelle était d'agir en hommes de science instruits à observer. Hugh J. Miser (Operational Research 22, 903) considère la recherche opérationnelle comme science, notant que ses progrès sont en effet de nature cyclique.La présente étude délimite explicitement les attributs de la méthode de la simulation. Il est démontré que la simulation est à la fois un art et une science; sa méthode, lorsqu'utilisée correctement, repose sur l'observation validée et le modèle vérifié.L'étude délimite les moyens actuels dont nous disposons pour vérifier et valider cycliquement les modèles bâtis à l'aide d'ordinateurs, établissant ainsi leur crédibilité. La nature complexe des phénomènes étudiés par les sciences sociales peut être comprise à l'aide de la simulation: la méthode dont se servent les hommes de science qui étudient les systèmes (les scientistes systémiques).相似文献
