AbstractWeak convergence and moment convergence issues are investigated for the New Better than Average Failure Rate (NBAFR) family (introduced by Loh (1984)). We explore the validity of these results in the context of a more general ageing class that we introduce. We prove some new properties of this class and derive its interrelationships with other non-monotonic ageing families. Reliability and moment bounds are obtained and an interesting characterization of exponentiality is proved. Special cases of our results lead to new theorems for the NBAFR class. Finally weak convergence and related issues are established for this class. 相似文献

Many organizational change projects fail — despite a well thought out concept, professional project management and a binding implementation timetable. The reason why the expected success doesn’t materialize often lies with the missing maintenance. Once the project is officially completed and the client and project manager withdraw, the manner in which the organization will take up these changes is seldom systematically dealt with. Difficulties often arise when no discrete stabilizing measures are planned. We have derived four central action areas which will be clarified by way of practical examples. It will also be shown what is important to pay attention to in the stabilization phase so that a lasting success of the organizational change project can be ensured. 相似文献

Detecting parameter shift in garch models 总被引:1,自引:0,他引:1
Chia-Shang James Chu 《Econometric Reviews》1995,14(2):241-266
This paper applies recent theories of testing for parameter constancy to the conditional variance in a GARCH model. The supremum Lagrange multiplier test for conditional Gaussian GARCH models and its robustified variants are discussed. The asymptotic null distribution of the test statistics are derived from the weak convergence of the scores, and the critical values from the hitting probability of squared Bessel process.
Monte Carlo studies on the finite sample size and power performance of the supremum LM tests are conducted. Applications of these tests to S&P 500 indicate that the hypothesis of stable conditional variance parameters can be rejected. 相似文献

To effectively manage planned change and understand differences in leaders’ and recipients’ responses to it, it is essential to understand how change is cognitively represented by organization members. In this theory-development article, we draw upon construal-level theory (CLT) and conceptually explore the role of change construal level in explaining responses to organizational change. We discuss differences between change leaders’ and recipients’ change construals, and differences in the relationships between change construal level and the response to change as a function of the change activities taking place. Specifically, we argue that high-level (i.e., abstract) construals of change will facilitate the effective initiation of change when the focus is on equilibrium-breaking activities, and that low-level (i.e., concrete) construals will facilitate the effective implementation of change when the focus is on institutionalization of the change. We further propose that leaders’ engagement in visionary leadership increases the likelihood that their generally higher level construal of change will be integrated into recipients’ change construals, elaborating and elevating them, and that recipients’ engagement in upward prohibitive voice behaviors will increase the likelihood that their generally lower construal of change will be integrated into leaders’ change construals, elaborating and concretizing them. We discuss theoretical and practical implications of our framework. 相似文献
