Sets of relatively short time series arise in many situations. One aspect of their analysis may be the detection of outlying
series. We examine the performance of standard normal outlier tests applied to the means, or to simple functions of the means,
of AR(1) series, not necessarily of equal lengths. Although unequal lengths of series implies that the means have unequal
variances, that are only known approximately, it is shown that nominal significance levels hold good under most circumstances.
Thus a standard outlier test can usefully be applied, avoiding the complication of estimating the time series' parameters.
The test's power is affected by unequal lengths, being higher when the slippage occurs in one of the longer series 相似文献

Empirical applications of poverty measurement often have to deal with a stochastic weighting variable such as household size.
Within the framework of a bivariate distribution function defined over income and weight, I derive the limiting distributions
of the decomposable poverty measures and of the ordinates of stochastic dominance curves. The poverty line is allowed to depend
on the income distribution. It is shown how the results can be used to test hypotheses concerning changes in poverty. The
inference procedures are briefly illustrated using Belgian data.

Singh et al. ([13]) pointed out that the Randomized response (RR) technique proposed by Moors ([9]) is not desirable because
it fails to protect the confidentiality of the respondents and they provided two alternative strategies free from the above
drawback but limited to SRSWOR sampling only. In this paper, generalization of one of the strategies is provided for complex
survey designs, wider class of estimators and for quantitative characteristics. Relative efficiency of the modified strategy
is tested through empirical investigations.

Eika Tai 《Asian Ethnicity》2007,8(1):5-23
Korean ethnic education in Japanese public schools has played an important role in the persistence of Korean ethnicity in Japan. In Osaka Prefecture, it began as an educational movement at the end of the 1960s. Japanese and Korean activists who led the movement had different political commitments and developed two approaches. Those interested in Korean homeland politics stressed the importance of teaching the ethnic culture of the homeland and tried to develop an ethno-national identity among Korean children. Those involved in civil rights politics in the context of Japan focused on the problem of ethnic discrimination and facilitated the formation of a political subjectivity among Korean children. The old practice of Korean ethnic education is a form of multicultural education and provides many useful ideas for today's multiculturalist teachers in Japan, who are dealing with children of newcomer foreigners. 相似文献

It is known that the Henderson Method III (Biometrics 9:226–252, 1953) is of special interest for the mixed linear models
because the estimators of the variance components are unaffected by the parameters of the fixed factor (or factors). This
article deals with generalizations and minor extensions of the results obtained for the univariate linear models. A MANOVA
mixed model is presented in a convenient form and the covariance components estimators are given on finite dimensional linear
spaces. The results use both the usual parametric representations and the coordinate-free approach of Kruskal (Ann Math Statist
39:70–75, 1968) and Eaton (Ann Math Statist 41:528–538, 1970). The normal equations are generalized and it is given a necessary
and sufficient condition for the existence of quadratic unbiased estimators for covariance components in the considered model. 相似文献

赛缪尔·普芬道夫是17世纪德国法哲学的开创者,是近代世界范围内最杰出的自然法学思想家.普芬道夫对法学的贡献主要表现在他对自然法的捍卫上,作为古典自然法学派在德国的主要代表,其著作中处处充满着自然法思想,尤其是契约论思想更是影响深远.在自然法学说方面,普芬道夫的思想联结着格老秀斯和霍布斯.与其他古典自然法思想家不同,他特别重视对义务的研究. 相似文献
