In this paper, the quantile-based flattened logistic distribution has been studied. Some classical and quantile-based properties of the distribution have been obtained. Closed form expressions of L-moments, L-moment ratios and expectation of order statistics of the distribution have been obtained. A quantile-based analysis concerning the method of matching L-moments estimation is employed to estimate the parameters of the proposed model. We further derive the asymptotic variance–covariance matrix of the matching L-Moments estimators of the proposed model. Finally, we apply the proposed model to simulated as well as two real life datasets and compare the fit with the logistic distribution. 相似文献

“再现说”是 20世纪中国艺术理论史中占主导地位的艺术理论,它影响了 20世纪中国艺术实践和艺术理论的整体格局,也影响了人们对艺术起源、艺术本质的看法。20世纪中国社会的动荡,使“再现说”为承载社会责任而偏离了艺术对它的要求。因此,要结合各种观点的语境分析其合理性,并结合“表现说”来分析其得失。 相似文献

Generalized method of moments (GMM) is used to develop tests for discriminating discrete distributions among the two-parameter family of Katz distributions. Relationships involving moments are exploited to obtain identifying and over-identifying restrictions. The asymptotic relative efficiencies of tests based on GMM are analyzed using the local power approach and the approximate Bahadur efficiency. The paper also gives results of Monte Carlo experiments designed to check the validity of the theoretical findings and to shed light on the small sample properties of the proposed tests. Extensions of the results to compound Poisson alternative hypotheses are discussed. 相似文献

Bias Correction in the Dynamic Panel Data Model with a Nonscalar Disturbance Covariance Matrix 总被引:1,自引:0,他引:1

Approximation formulae are developed for the bias of ordinary and generalized Least Squares Dummy Variable (LSDV) estimators in dynamic panel data models. Results from Kiviet [Kiviet, J. F. (1995), on bias, inconsistency, and efficiency of various estimators in dynamic panel data models, J. Econometrics68:53-78; Kiviet, J. F. (1999), Expectations of expansions for estimators in a dynamic panel data model: some results for weakly exogenous regressors, In: Hsiao, C., Lahiri, K., Lee, L-F., Pesaran, M. H., eds., Analysis of Panels and Limited Dependent Variables, Cambridge: Cambridge University Press, pp. 199-225] are extended to higher-order dynamic panel data models with general covariance structure. The focus is on estimation of both short- and long-run coefficients. The results show that proper modelling of the disturbance covariance structure is indispensable. The bias approximations are used to construct bias corrected estimators which are then applied to quarterly data from 14 European Union countries. Money demand functions for M1, M2 and M3 are estimated for the EU area as a whole for the period 1991: I-1995: IV. Significant spillovers between countries are found reflecting the dependence of domestic money demand on foreign developments. The empirical results show that in general plausible long-run effects are obtained by the bias corrected estimators. Moreover, finite sample bias, although of moderate magnitude, is present underlining the importance of more refined estimation techniques. Also the efficiency gains by exploiting the heteroscedasticity and cross-correlation patterns between countries are sometimes considerable. 相似文献

翻译是一种双语行为。既要侧重于研究原语、解读原文文本,又要侧重于研究译语,在原文与译文文本表现法之间找到一个平衡点。表现法的目的是探讨如何将“获得的意义”落实到得体的目的语文本中。本文着重研究翻译表现法的基本原则,根据译者对意义把握和意义表达程度的深浅,翻译再现的层次可分为表层翻译、中介层翻译和深层翻译。 相似文献

The present paper aims to consider the cultural function of television as a technology for the creation of a public memory. The television system records past images, preserves them, and broadcasts various historical programs. A viewer owns the public memory jointly, through watching/consuming programs. However, the process of production and consumption of programs is linked with the exclusion of other historical memories from the public space. After all, the creation of public memories in depth is related to social power. Through the analysis in concrete terms of a series of programs of Project X and the second episode of the Nippon Hoso Kyokai (NHK; Japan Broadcasting Corporation) series, Special Edition: Judging War, the relationship between the organization of public memories and social power is explored. Project X depicts the challenges of engineers of middle standing who initiated new industrial and technological developments in the 1960s and 1970s. Special Edition: Judging War is based on coverage of the Women's International War Crimes Tribunal on Japan's Military Sexual Slavery. This program was subjected to revision on the eve of its broadcast. What forms of expression were eliminated? These two programs should help us define more clearly what the Japanese media selects for incorporation into the public memory. 相似文献

The purpose of this paper is threefold. First, we obtain the asymptotic properties of the modified model selection criteria proposed by Hurvich et al. (1990. Improved estimators of Kullback-Leibler information for autoregressive model selection in small samples. Biometrika 77, 709–719) for autoregressive models. Second, we provide some highlights on the better performance of this modified criteria. Third, we extend the modification introduced by these authors to model selection criteria commonly used in the class of self-exciting threshold autoregressive (SETAR) time series models. We show the improvements of the modified criteria in their finite sample performance. In particular, for small and medium sample size the frequency of selecting the true model improves for the consistent criteria and the root mean square error (RMSE) of prediction improves for the efficient criteria. These results are illustrated via simulation with SETAR models in which we assume that the threshold and the parameters are unknown. 相似文献

The paper considers simultaneous estimation of finite population means for several strata. A model-based approach is taken, where the covariates in the super-population model are subject to measurement errors. Empirical Bayes (EB) estimators of the strata means are developed and an asymptotic expression for the MSE of the EB estimators is provided. It is shown that the proposed EB estimators are “first order optimal” in the sense of Robbins [1956. An empirical Bayes approach to statistics. In: Proceedings of the Third Berkeley Symposium on Mathematical Statistics and Probability, vol. 1, University of California Press, Berkeley, pp. 157–164], while the regular EB estimators which ignore the measurement error are not. 相似文献
