Summary In this paper it is investigated whether robust estimation procedures for the parameters of a regression model are also applicable when the observations are generated by the errors-in-variables model. Specifically, attention is paid to bounded-influence estimators, i.e. estimators that are constructed in such a way that the influence of a single observation on the outcome of the estimator is bounded. Both the classical errors-in-variables model and models with contaminated observational errors are considered.The authors are indebted to a referee for his valuable comments on an earlier version of this paper. 相似文献
Summary The problem of estimating the slope of a linear relationship between two jointly normally distributed random variables is considered when outliers may occur in the explanatory variable. It will be studied as a special case of an errors-in-variables problem where the explanatory variable is measured which a nonnormally distributed error. In this more general model and under certain conditions a consistent estimator can be given with a normal limiting distribution. Applications to cases of outliers in the explanatory variable will be presented. 相似文献
In this paper we construct all possible orthogonal arrays OA(18,q, 3,2) with 18 runs and 3 ≤ q ≤ 7 columns and present those that are nonisomorphic. A discussion on the novelty and the superiority of many of the designs
found in terms of isomorphism and generalized minimum aberration has been made.

The linkage between development and health is clearly spelt out in the definition of primary health care by the World Health Organisation. There is a widespread and growing disillusionment with the traditional Western approach to health care which fails to meet the real demands of the Third World situation.
This paper looks briefly at conditions in the developing world and the strategy proposed by the W H O to attempt to meet the objective of health for all by the year 2000 and refers to the South African situation. 相似文献
"This paper extends the standard (two-factor, one-good) model of international factor movements, to include unemployment due to a minimum-income guarantee within the capital-abundant country. From this country's perspective, we establish important departures from previous (full-employment) results. Most notably, our analysis shows that: (1) free factor mobility is worse than no mobility; (2) the optimal degree of labour migration is zero; and (3) national welfare can always be maximized by an optimal flow of capital. The analysis is then extended to examine: (1) illegal migration; (2) subsidization of employment; and (3) alternative views of unemployment." 相似文献
This paper discusses the impact of a redistribution of current income from the White to the Black population on the distribution of sectoral output, and total employment by means of a semi‐closed input‐output model.
The results show that a redistribution of current income towards Black households — which no doubt will have positive social and political repercussions — has a non‐negative effect on GDP and a definite positive effect on the performance of sectors with a high private consumption expenditure component, as well as on total employment. 相似文献
This research examines the effect of an alliance competence on resource-based alliance success. The fundamental thesis guiding
this research is that an alliance competence contributes to alliance success, both directly and through the acquisition and
creation of resources. Using survey data gathered from 145 alliances, empirical tests of the hypotheses provide support for
the posited explanation of alliance success. The findings indicate that an alliance competence is not only antecedent to the
resources that are necessary for alliance success but also to alliance success itself.

When do consumers complain? This study probes this question by developing a conceptual framework that includes multiple theoretical perspectives, empirically testing a portion of the proposed model, and using dissatisfaction/complaint data from three different service industries. The hypothesized model uses multidimensional consumer complaint response estimates including voice, private, and third-party responses as dependent variables. Results support several proposed relationships, provide a high level of explained variance, and indicate a moderating role for dissatisfaction intensity. The complaint response estimates are characterized by disparate influence pathways, and expectancy value judgments emerge as critical determinants with positive and negative crossover effects. Attitude toward complaining is more dominant under low dissatisfaction intensity than it is under the high dissatisfaction condition. Important differences emerge across service categories. Implications of this work for managers and researchers in understanding when consumers complain are enumerated. 相似文献
In recent years, many of the basic assumptions underlying organizational conflict research have changed, drawing into question
the validity of some previous research findings. Operating from the perspective that conflict is complex, multidimensional,
and context specific, this research takes a fresh look at key conflict antecedents, mediators, and consequences in the context
of the innovation process. The study investigates the relationships among five behavioral conflict-handling strategies, destructive
and constructive conflict, and innovation performance as perceived by 290 R & D and marketing department managers. Empirical
results both support and question some of the previous findings in conflict research. The results indicate that integrating,
accommodating, compromising, forcing, and avoiding conflict-handling strategies can have different impacts on constructive
and destructive conflict in an innovation context.
