We describe a simple method for nonparametric estimation of a distribution function based on current status data where observations
of current status information are subject to misclassification. Nonparametric maximum likelihood techniques lead to use of
a straightforward set of adjustments to the familiar pool-adjacent-violators estimator used when misclassification is assumed
absent. The methods consider alternative misclassification models and are extended to regression models for the underlying
survival time. The ideas are motivated by and applied to an example on human papilloma virus (HPV) infection status of a sample
of women examined in San Francisco. 相似文献

钓鱼岛问题,是历史遗留在中日之间的领土主权归属问题。钓鱼岛自古以来就是中国领土,日本对钓鱼岛的实际占领,以及日方在钓鱼岛问题上所持的强硬立场,使钓鱼岛问题日益复杂化,已成为中日关系中最为敏感的问题之一。它不仅关系到中日关系的发展,而且涉及亚太地区战略格局发展的大局。中日必须从21世纪两国关系发展大局出发,妥善处理分歧,和平解决争端。 相似文献

In this paper we share our collaborative experience of making a video in which disabled women present their lives as they wish to portray them. We undertook what we hope will be perceived as emancipatory research, in which disabled and non-disabled women work together to create audio-visual teaching materials. We include a preliminary discussion about the representation of disability on British television broadcasts between October 1991 and March 1992. We look at negative imagery, charity fund raising, and positive images. The paper uses comments by disabled broadcasters and disabled academics, and reflects on their work. 相似文献

This paper is a review of research in Chicago that linked analyses of vegetation structure with forest functions and values. During 1991, the regions trees removed an estimated 5575 metric tons of air pollutants, providing air cleansing worth 9.2 million. Each year they sequester an estimated 315 800 metric tons of carbon. Increasing tree cover 10% or planting about three trees per building lot saves annual heating and cooling costs by an estimated 50 to 90 per dwelling unit because of increased shade, lower summertime air temperatures, and reduced neighborhood wind speeds once the trees mature. The net present value of the services trees provide is estimated as 402 per planted tree. The present value of long-term benefits is more than twice the present value of costs. 相似文献
