We consider the estimation of the 90 and 95 percentiles of a normal distribution and also the construction of one-sided 90% and 95% -normal ranges. Three methods are proposed -the sample percentile method, and two based on kernel estimates of the density function using Fryer's method and the leaving-one-out method for choosing a smoothing parameter. A simulation study compares the methods in terms of bias, variance and mean square error of the population percentile estimates and of the eovers of the consequent normal ranges. 相似文献

AbstractOpen Data (OD) is an emerging term in the process of defining how scientific data may be published and re-used without price or permission barriers. Scientists generally see published data as belonging to the scientific community, but many publishers claim copyright over data and will not allow its re-use without permission. This is a major impediment to the progress of scholarship in the digital age. This article reviews the need for Open Data, shows examples of why Open Data are valuable, and summarizes some early initiatives in formalizing the right of access to and re-use of scientific data. 相似文献

ABSTRACTIn this paper, we provide conditions under which some bivariate dependence structures are preserved under bivariate weighted distributions. Bivariate weighted distributions whose dependence structure is the same as the original distribution are characterized. Finally, we discuss some examples to show the usefulness of our results. 相似文献

Sereral preservation results for the mean residual life (mr) ordering are given. In particular, we show that the mr-ordering is preserved under convolutions, mixtures and weak convergence. 相似文献

AbstractThis installment of Electronic Journal Forum describes the steps taken to revise Integrating Resources: A Cataloging Manual, which was first published in 2003. The revision reflects recent changes in MARC 21 coding and Program for Cooperative Cataloging practices, including provider-neutral record guidance. Examples in the manual were reviewed and purged of inconsistencies in coding. 相似文献

Web 2.0, Library 2.0, and the Hyperlinked Library 总被引:3,自引:0,他引:3
Discussions surrounding the concepts of Web 2.0/Library 2.0 are increasing among the library community. This column outlines key principles behind Web 2.0 and provides a brief explanation of social tools, such as blogs, RSS feeds, podcasting, and wikis. The author also provides specific uses and applications of these tools within the library environment to illustrate the Library 2.0 concept. An open framework for library communication or hyperlinked library can result if Library 2.0 philosophies are fully utilized. 相似文献
