Assessing accuracy of a continuous screening test in the presence of verification bias

Summary.  In studies to assess the accuracy of a screening test, often definitive disease assessment is too invasive or expensive to be ascertained on all the study subjects. Although it may be more ethical or cost effective to ascertain the true disease status with a higher rate in study subjects where the screening test or additional information is suggestive of disease, estimates of accuracy can be biased in a study with such a design. This bias is known as verification bias. Verification bias correction methods that accommodate screening tests with binary or ordinal responses have been developed; however, no verification bias correction methods exist for tests with continuous results. We propose and compare imputation and reweighting bias-corrected estimators of true and false positive rates, receiver operating characteristic curves and area under the receiver operating characteristic curve for continuous tests. Distribution theory and simulation studies are used to compare the proposed estimators with respect to bias, relative efficiency and robustness to model misspecification. The bias correction estimators proposed are applied to data from a study of screening tests for neonatal hearing loss.

苏秦“合纵术”的辩证法底蕴

一般地说 ,苏秦“合纵术”被世人冠之以权变之术。但从哲学角度予以考察 ,可以发现合纵术具备的深厚辩证法底蕴 ,主要表现在 3个方面 :合纵术建立的理论依据是客观存在的现实矛盾 ;合纵术构思的思维方法是矛盾分析方法 ;合纵术全面体现了矛盾在事物发展中的作用。因此 ,苏秦的合纵术自发地合乎唯物辩证法的基本要求 ,是处于朴素状态的有效的社会整合方法 ,对我国当前解决社会矛盾、稳定社会秩序 ,意义很大     

Gini’s nuclear family

The purpose of this paper is to justify the use of the Gini coefficient and two close relatives for summarizing the basic information of inequality in distributions of income. To this end we employ a specific transformation of the Lorenz curve, the scaled conditional mean curve, rather than the Lorenz curve as the basic formal representation of inequality in distributions of income. The scaled conditional mean curve is shown to possess several attractive properties as an alternative interpretation of the information content of the Lorenz curve and furthermore proves to yield essential information on polarization in the population. The paper also provides asymptotic distribution results for the empirical scaled conditional mean curve and the related family of empirical measures of inequality.      

大学文化建设探析

论审理医疗纠纷案件对美国法庭“专家证人制度”的借鉴——由中美两个案例比较谈起

近阶段,医疗纠纷冲突凸显,大量的矛盾往往最终汇集到法院。而审理医疗纠纷案件时,法官面临诸多法律困境,尤其是科学证据的采纳问题。分析认为,借鉴美国"专家证人"制度,人民法院应设立"专家辅助人",可以较为有效地解决这些问题。
