The Gauss-Newton regression (GNR) is widely used to compute Lagrange multiplier statistics. A regression described by Milliken and Graybill yields an exact F test in a certain class of nonlinear models which are linear under the null. This paper shows that the Milliken-Graybill regression is a GNR. Hence one interpretation of Milliken-Graybill is that they identified a class of nonlinear models for which the GNR yields an exact test. 相似文献

When presented as graphical illustrations, regression surface confidence bands for linear statistical models quickly convey detailed information about analysis results. A taut confidence band is a compact set of curves which are estimation candidates for the unobservable, fixed regression curve. The bounds of the band are usually plotted with the estimated regression curve and may be overlaid by a scatter-plot of the data to provide an integrated visual impression. Finite-interval confidence bands offer the advantages of clearer interpretation and improved efficiency and avoid visual ambiguities inherent to infinite-interval bands. The definitive characteristic of a finite-interval confidence band is that it is only necessary to plot it over a finite interval in order to visually communicate all its information. In contrast, visual representations of infinite-interval bands are not fully informative and can be misleading. When an infinite-interval band is plotted, and therefore truncated, substantial information given by its asymptotic behavior is lost. Many curves that are clearly within the plotted portion of the infinite interval confidence band eventually cross a boundary. In practice, a finite-interval band can always be easily obtained from any infinite-interval band. This article focuses on interpretational considerations of symmetric confidence bands as graphical devices. 相似文献

This article draws upon case-study research into human resource development (HRD) within three small organizations in the north west of England. It positions the case-study work within an overall framework of doctoral research and summarizes the research design; discusses the characteristics and values of small organizations and how they influence HRD policies and practices: presents findings and conclusions about HRD in the case-study organizations, focusing in particular upon one case in the voluntary sector; compares and contrasts the different models of HRD in the three cases; and concludes with some suggestions for further research. 相似文献

Abstract Looking for a world model for the manufacturing information flow diagram has brought us to the conclusion that it is impossible to build an all-encompassing, all-inclusive system. The redundancy and overlap would make the system excessively complex and ineffective. The best way to generalize a model of this type is to simplify. The result is that we eliminate nearly the entire production control mechanism that is found in the labour intensive MRP system (Fig. 1). We come up with a system that is much closer to the material intensive JIT system (Fig. 2). The conclusion is that effective production control requires that you choose which resource you wish to optimize, and then select a system that controls the plant around the selected resource base. This is the function of books like International Management and Production. A second conclusion would be that complexity (MRP—Fig. 1) gains very little over simplicity (JIT—Fig. 2 or World Model—Fig. 4) in productivity or efficiency. As Shozo Hibino says in his book Breakthrough Thinking, we need to run our plants smarter, not harder. 相似文献

In this paper we obtain several influence measures for the multivariate linear general model through the approach proposed by Muñoz-Pichardo et al. (1995), which is based on the concept of conditional bias. An interesting charasteristic of this approach is that it does not require any distributional hypothesis. Appling the obtained results to the multivariate regression model, we obtain some measures proposed by other authors. Nevertheless, on the results obtained in this paper, we emphasize two aspects. First, they provide a theoretical foundation for measures proposed by other authors for the mul¬tivariate regression model. Second, they can be applied to any linear model that can be formulated as a particular case of the multivariate linear general model. In particular, we carry out an application to the multivariate analysis of covariance. 相似文献

In this paper we give a class of row-column designs with the property that the i-th row and the j-th column have precisely r treatments in common. A conjecture that such designs are quasi-factorial is disproved by showing that the designs given in this paper are not quasi-factorial. It is also shown that the designs given here are nearly optimal. 相似文献

This article presents the findings of an Arts and Humanities Research Board project on London’s Millennium Dome exposition in the year 2000. The Dome was generally considered to be a cultural disaster in the news media and public conversation. It became a political embarrassment for Britain’s New Labour government but did not prove damaging in the 2001 general election. The article does not dispute the media’s damnation of the Dome but questions its acuity. It also questions the managerialist perspective on the Dome’s ‘failure’ whilst taking into account claims regarding a managerial ‘turnaround’ and an ‘under-reported success’. Empirical evidence and theoretical analysis concerning the political economy of the Dome’s production, its representational meanings and visitor reception provide a more complex and multidimensional explanation. Corporate sponsorship played a key role in the cultural disaster and, in this particular case study, it exemplifies social democracy’s symbolic as well as material coalescence with neo-liberalism. A distinction is made between associative and deep sponsorship that is illustrated with examples from the Dome. A typology of generous and reflexive visiting is also formulated in order to analyse the visitor data. 相似文献

Disturbances in affect have been linked to problem behavior in adolescence and future psychopathology, but little is known about how such disturbances manifest themselves in everyday contexts. This study investigated daily mood in Dutch 7th graders, aged 11–14. Cluster analysis of problem measures distinguished high-risk (n=25) and low-risk (n=106) subgroups. Participants completed experience-sampling reports of mood, social context, and location nine times daily for 5 days. Multilevel regression analyses of four mood measures confirmed higher anxiety and depressed mood in the high-risk group. Moods varied by location and social context, with significant differences between groups in two specific social contexts. First, when with family, low-risk adolescents felt less depressed than when alone, whereas high-risk adolescents felt more depressed. Second, high-risk adolescents showed more pronounced anxiety in social situations outside the network of family and friends. These findings point to everyday social contexts in which young adolescents with emotional and behavioral problems appear to be particularly vulnerable. 相似文献
