On an adaptive transformation–retransformation estimate of multivariate location

An affine equivariant estimate of multivariate location based on an adaptive transformation and retransformation approach is studied. The work is primarily motivated by earlier work on different versions of the multivariate median and their properties. We explore an issue related to efficiency and equivariance that was originally raised by Bickel and subsequently investigated by Brown and Hettmansperger. Our estimate has better asymptotic performance than the vector of co-ordinatewise medians when the variables are substantially correlated. The finite sample performance of the estimate is investigated by using Monte Carlo simulations. Some examples are presented to demonstrate the effect of the adaptive transformation–retransformation strategy in the construction of multivariate location estimates for real data.

张謇师范教育思想研究述评

师范教育,是张謇创办教育事业的起点和基点,又为他心力所注。张謇在长期的师范教育实践中,特别是在通州师范学校创办过程中,形成了富有个性的师范教育思想。对张謇师范教育思想的研究实际上从他在世时已经开始,尤其从上世纪八十年代以来,研究的深度和广度有了进一步的拓展,取得了一定的成果,主要集中在张謇在中国近代师范教育史上的地位、张謇创办师范教育的原因、张謇师范教育思想主要内容、张謇师范教育思想评价等方面。     

20世纪上半叶康区师范教育发展述论

文章对20世纪上半叶康区师范教育发展的背景进行了较为全面的考察,对康区师范教育发展概况作了详尽的梳理。不难发现,康区师范教育经历了艰难而曲折的发展历程,但其间闪光之处可圈可点:既有民众的自觉自为,又有当局的不懈努力;既有地方政府与乡村名流的解囊相助,又有中央政府的政策支持,使康区师范教育从附设的简易师范班发展到边疆师范区,为当地教育、经济、文化等的发展作出了积极的贡献。     

关于政府如何转变职能适应中国新常态的战略思考

进入21世纪以来,伴随着经济全球一体化的快速发展,我国政府职能虽经历过几次较大规模的调整与转变,但是政府职能并没有发生实质性的改变。目前面对着国际、国内的新形势,关于政府如何适应中国新常态以及如何在新常态下提高自身的应对能力,这些问题与政府是否能够有效实现职能转变有着密切关系。本文主要从中国新常态的背景入手,对中国当前面临的机遇与挑战作出描述,进而对新常态下政府如何实现有效的职能转变给出一些建议。

On implementation of a test for Kronecker product covariance structure for multivariate repeated measures data

Under the assumption of multivariate normality the likelihood ratio test is derived to test a hypothesis for Kronecker product structure on a covariance matrix in the context of multivariate repeated measures data. Although the proposed hypothesis testing can be computationally performed by indirect use of Proc Mixed of SAS, the Proc Mixed algorithm often fails to converge. We provide an alternative algorithm. The algorithm is illustrated with two real data sets. A simulation study is also conducted for the purpose of sample size consideration.

Nonparametric estimation of spatial segregation in a multivariate point process: bovine tuberculosis in Cornwall, UK

Summary.  The paper is motivated by a problem in veterinary epidemiology, in which spatially referenced breakdowns of bovine tuberculosis are classified according to their genotype and year of occurrence. We develop a nonparametric method for addressing spatial segregation in the resulting multivariate spatial point process, with associated Monte Carlo tests for the null hypothesis that different genotypes are randomly intermingled and no temporal changes in spatial segregation. Our spatial segregation estimates use a kernel regression method with bandwidth selected by a multivariate cross-validated likelihood criterion.
