An investigation of transformation-based prediction interval for the Weibull median life

Statistical inference based on the Weibull distribution, a distribution widely used in reliability and survival analysis, is usually difficult as it often involves numerical computation and approximation. However, this distribution can be transformed to near-normality by a simple power transformation. Based on this transformation, a prediction interval (PI) for its median can be easily constructed through an inverse transformation. The procedure for selecting the best power transformation through minimizing Kullback-Leibler information is described. The property of this transformation-based PI is investigated. Simple correction factors are also proposed. It is shown that the transformation-based PI with corrections performs well, irrespective of the sample size and parameter values. Simulation results show that the new PI generally outperforms the existing PI. Numerical examples are given for illustration.

中间选民理论在农民工市民化政策制定中的运用——基武汉市436位农民工的实证研究

The Median Voter Theory is an important theory in the neo-political economics. It can be applied to solve the collective choice paradox and analyze the policy making for the citizenization of peasant workers. Adopting the method of factor analysis, this paper makes an empirical study on peasant workers’ preference for citizenization. We find that there is a paradox of future residence preference and self-identification in peasant workers. On this basis, peasant workers are divided into 5 subgroups, and it is found that the median undecided peasant workers are the median voters. Based on the analysis of the median undecided peasant worker’s complaints and appeals, it is proposed that the country should strengthen the vocational training system, establish a social security system, expand the agricultural reform and promote educational reform to facilitate the citizenization of peasant workers. __________ Translated from Guanli Shijie 맜理世界 (Management World), 2007, (4): 40–67

中国金融业分业经营与混业经营研究

实践表明，混业经营有助于增强金融机构的国际竞争力，促进一国经济的发展，目前已成为全球金融业发展的趋势。就我国而言，从长远的角度来看，混业经营是金融业的必然选择，但短期内尚不具备过渡的条件。由于我国已加入WTO，所以目前应抓住机遇，采取相应的对策，为将来混业经营作好准备。     

Poverty comparisons with dependent samples

Standard inference procedures for poverty comparisons require samples to be independent. For many commonly used income samples, however, this requirement is not fulfilled since samples are rotated. This article introduces an easy‐to‐use method of correction for sample dependency. We also apply the method to test changes in US poverty in the 1990s and to evaluate the marginal effects of public assistance on poverty before and after the recent welfare reform.
