Confidence Intervals for Current Status Data

Abstract.  The likelihood ratio statistic for testing pointwise hypotheses about the survival time distribution in the current status model can be inverted to yield confidence intervals (CIs). One advantage of this procedure is that CIs can be formed without estimating the unknown parameters that figure in the asymptotic distribution of the maximum likelihood estimator (MLE) of the distribution function. We discuss the likelihood ratio-based CIs for the distribution function and the quantile function and compare these intervals to several different intervals based on the MLE. The quantiles of the limiting distribution of the MLE are estimated using various methods including parametric fitting, kernel smoothing and subsampling techniques. Comparisons are carried out both for simulated data and on a data set involving time to immunization against rubella. The comparisons indicate that the likelihood ratio-based intervals are preferable from several perspectives.     

出走与反抗:叛逆女性之路--娜拉与娜嘉形象之比较

对挪威戏剧家易卜生笔下的娜拉与俄国小说家契诃夫笔下的娜嘉这两个文学形象进行了分析比较。娜拉和娜嘉同是为了跟不幸的命运抗争,做出了离家出走的抉择,她们的出走表现了觉醒女性的反叛和坚强,但也有着不同的意义,娜拉的出走是绝望地逃离,而娜嘉的出走,则充分展示了知识女性的理智与自信,娜嘉比娜拉走得更远更清醒。     

Poor Mothers and Habits of Hiding: Participatory Methods in Poverty Research

Poor mothers have long‐standing habits of hiding their lives in response to punitive authorities and stigma. We identify practices of hiding daily life, and we describe participatory research approaches for and ethical concerns in learning more about poor women's critical insights and survival strategies.

试析中国诗性智慧语境下的《镜花缘》

在理性的语境下解读充满浪漫主义色彩的<镜化缘>,一方面扭曲了固有的鲜活灵动的审美旨趣,另一方面遮蔽了艺术思维与人类思维的血脉渊源.因此,只有把<镜化缘>放到中国诗性智慧的独特语境下,才能使文本凸显中国诗性文化特有的生命一体化的哲学维度以及女性崇拜的原形题旨.     

Semiparametric linear transformation models for current status data

Current status data arise when the death of every subject in a study cannot be determined precisely, but is known only to have occurred before or after a random monitoring time. The authors discuss the analysis of such data under semiparametric linear transformation models for which they propose a general inference procedure based on estimating functions. They determine the properties of the estimates they propose for the regression parameters of the model and illustrate their technique using tumorigenicity data.     

Dimensions of occupational inequality and Duncan's socioeconomic index

Using the original 1962 Blau and Duncan data for white males, I compare relative amounts of inequality in the distributions of occupational prestige, earnings, autonomy, and job skills. Also assessed are the degree of status rigidity (or intercorrelations) among these four dimensions of occupational inequality and the simultaneous relations among these four dimensions in a father-to-son occupational mobility model. These findings are compared to those obtained with Duncan's socioeconomic index to determine whether additional information can be obtained when using independent measures representing the multiple dimensions of occupational inequality versus using the SEI alone. Only minor discrepancies are found, and these relate to autonomy and earnings.An earlier version of this paper was presented at the 1985 Pacific Sociological Association meetings.
