We consider the problem of modelling a long-memory time series using piecewise fractional autoregressive integrated moving average processes. The number as well as the locations of structural break points (BPs) and the parameters of each regime are assumed to be unknown. A four-step procedure is proposed to find out the BPs and to estimate the parameters of each regime. Its effectiveness is shown by Monte Carlo simulations and an application to real traffic data modelling is considered. 相似文献

The importance of good governance is praised by many academics and practitioners. The prominence of the subject suggests that measurement is important. However, setting out to measure the quality of governance empirically is controversial. Doubts regarding the feasibility and meaningfulness of this undertaking are widespread in the literature. Recognizing the potential caveats, the current article discusses a set of guidelines for structuring a theoretically sound local governance assessment tool based on the Decision Analysis and Operational Research literatures. The authors argue that using a multi-criteria model which employs several objective (quantitative and qualitative) indicators and relies on a participatory method to aggregate them is a suitable way of developing sensible Local Governance Indicators. The purpose here is to provide a detailed roadmap for any country (or region, or locality) willing to engage in the assessment of the quality of local governance. The real-world implementation of a model developed according to these guidelines could help raise awareness, promote good practices and increase the ‘governance literacy’ of citizens. By operationalizing good governance, analysts may also be able to further investigate the relationships between local governance practices and several socio-economic factors. 相似文献

There have been a number of procedures used to analyze non-monotonic binary data to predict the probability of response. Some classical procedures are the Up and Down strategy, the Robbins–Monro procedure, and other sequential optimization designs. Recently, nonparametric procedures such as kernel regression and local linear regression (llogr) have been applied to this type of data. It is a well known fact that kernel regression has problems fitting the data near the boundaries and a drawback with local linear regression is that it may be “too linear” when fitting data from a curvilinear function. The procedure introduced in this paper is called local logistic regression, which fits a logistic regression function at each of the data points. An example is given using United States Army projectile data that supports the use of local logistic regression when analyzing non-monotonic binary data for certain response curves. Properties of local logistic regression will be presented along with simulation results that indicate some of the strengths of the procedure. 相似文献

We investigate the convergence rates of uniform bias-corrected confidence intervals for a smooth curve using local polynomial regression for both the interior and boundary region. We discuss the cases when the degree of the polynomial is odd and even. The uniform confidence intervals are based on the volume-of-tube formula modified for biased estimators. We empirically show that the proposed uniform confidence intervals attain, at least approximately, nominal coverage. Finally, we investigate the performance of the volume-of-tube based confidence intervals for independent non-Gaussian errors. 相似文献

城镇化进程中农民集体所有土地转变为城市国有土地,在该过程中产生大量的土地增值收益。地方政府、用地企业、村委会和农民在土地增值收益分配中有不同的行为表现,其根本原因在于利益分配冲突。从不同主体行为角度对土地增值收益分配中利益冲突问题进行研究,有利于探讨利益冲突背后的原因并提出有针对性的政策建议。 相似文献

改革开放以来,我国经济发展取得了巨大成就,但也面临一些重大挑战,特别是本土企业加入、依赖跨国公司主导的产业链,在短期内得以迅速发展的同时,也导致本土产业链出现了断裂和碎片化的问题,这对本土企业的创新和发展是不利的。文章研究在我国建立以本土企业为主体的协同创新机制的基本规律和特点,为提高本土企业的创新能力提供借鉴。研究的主要发现是,这是一个复杂和曲折的过程,在这一过程的启动阶段和转折阶段,非经济因素或者至少是长期经济因素而不是短期经济因素具有独特的、非常重要的作用。 相似文献

In Ethiopia, the study and issue of center–periphery relations is not an easy task. It has remained complex and dynamics as it has been dictated and shaped by ever changing socio-economic relations, state ideology and structure. A case in point is Metekel region, which had been characterized by under development, lowland, hot climate and traditional way of life. Until post-1991developments, Metekel was peripheral in relation to the central state. It was an area of confrontation and conflict. Owing to the structural weakness of the centre, successive rulers of the area did not command effective control over it. Focusing on Gumuz, a Nilo-Saharan family, on one hand, and highlanders and new settlers, on the other, this essay examined the main features and dynamics of center–periphery relations, governance and conflicts in Metekel area. The sources, both primary and secondary, have been carefully examined based on the objectives of the study. 相似文献

Different from the majority of past research on gender gaps in political officeholding, we adopt an intersectionality framework and move beyond traditional individual factors to explore what implications certain elements in the political opportunity structure may have for women and men of color elected officials serving in county, municipal, and local school board offices. We argue that structural and contextual factors, such as type of institutions, election systems, and jurisdictional racial makeup, may influence the calculations women of color make concerning the accessibility of elective office. Using data from the Gender and Multiracial Leadership (GMCL) project, we find county offices to be the least, and seats on school boards the most, accessible to women of color. Of the types of electoral arrangements, we find multimember districts (MMD) to be the most significant variable predicting the likelihood of women of color in office. Although both Black and Latina women benefit from having a significant share of coethnics or nonwhites in jurisdictions, the two groups of women have an opposite relationship to their racial constituent makeup than that held by their male counterparts. 相似文献

Political reform after the departure of President Soeharto’s New Order (1966–1998) provided opportunities for previously oppressed social groups to express their concerns and to demand fair recognition. The results of this newly found freedom have been quite immediately visible in Jakarta, where social and political institutions spearheaded by Chinese originally sprouted. In the regions, political participation of ethnic Chinese has also grown; significantly in those regions with a large Chinese population. In West Kalimantan, the number of Chinese being elected to local parliaments in some regions has doubled. They have also contested numerous direct local executive elections since 2003 and have been successful in winning four posts: a mayor, a district head, a deputy district head, and a deputy governor. By looking at the case of West Kalimantan, this article will examine the factors behind the growth in Chinese political activism, the factors contributing to the success of Chinese candidates in elections, how the Chinese have influenced local and provincial politics, and the challenges they are facing. 相似文献
