A class of goodness-of-fit estimators is found to provide a useful alternative in certain situations to the standard maximum likelihood method which has some undesirable estimation characteristics for estimation from the three-parameter lognormal distribution. The class of goodness-of-fit tests considered include the Shapiro-Wilk and Filliben tests which reduce to a weighted linear combination of the order statistics that can be maximized in estimation problems. The weighted order statistic estimators are compared to the standard procedures in Monte Carlo simulations. Robustness of the procedures are examined and example data sets analyzed. 相似文献

This paper considers the situation where a stochastic process may display both long-range dependence (LRD) and intermittency. The existence of such a process is established in Anh et al. (1999). Existing works have commonly paid attention either to LRD or intermittency quite separately. This paper offers a convenient framework to study both effects simultaneously. A method is given to estimate and separate the two effects. The wavelet theory plays an essential role in this procedure. Numerical experiments on fractional Brownian motion and multiplicative cascade processes confirm the power of the method. 相似文献

The relative performance of a component of a series system in two different environments is considered. The conditional probability of the failure of the system due to the failure of the specified component given that the system failed before time t is regarded as a measure of relative importance of the component to the system. A U-statistic test for checking the equality of the relative importance of the component to the system in two different environments against the alternative that the relative importance is smaller in one of the environments, is proposed. Some simulation results for estimating the power of the test are reported. The proposed test is applied to one real data set and it is seen that a different aspect of the data is brought out by this comparison than that by the comparisons of the absolute importance functions such as the subsurvival functions, considered in earlier studies. 相似文献

Culture and Co‐residence: An Exploration of Variation in Home‐Returning among Canadian Young Adults*
Barbara A. Mitchell Andrew V. Wister Ellen M. Gee 《Revue canadienne de sociologie》2000,37(2):197-222
Cet article s'inscrit dans la lignée des études sur les dimensions culturelles de la cohabitation entre générations en examinant de près le comportement des jeunes adultes canadiens qui retournent vivre chez leurs parents. Nous explorons les rapports mutuels entre la famille et la diversité culturelle, entre le capital financier et le capital social, et entre le rythme et les mécanismes de transitions précoces qui se manifestent au cours d'une vie. Les modéles de hasards proportionnels sont appliqués à un sous‐échantillon de 2 549 jeunes adultes, àgés de 19 á 34 ans, en tenant compte des données de l'Enquete sociale générale, cycle 10, de 1995. L'une des principales conclusions tirées ici indique que les jeunes qui sont de langue maternelle anglaise sont beaucoup plus susceptibles de retourner chez leurs parents après un premier départ que ceux dont la langue maternelle est le français ou une autre langue. Les autres variables qui entrent en jeu sont le niveau d'education du père, le nombre de frères et de soeurs, le sexe, l'âge au moment du depart de la maison et la raison de ce départ. L'article aborde aussi les questions des responsabilités et des rôles des parents autour de la cinquantaine, et de la socialisation au sein de la famille au cours de la vie. This article offers a focussed examination of variation in home‐returning behaviour among Canadian young adults. Framed within the life course perspective, we explore the interrelationships among family and cultural diversity, financial and social capital, and the timing and pathways of early transitions. Proportional hazards analyses are performed on a subsample of 2,549 young adults aged 19–34, using data from the 1995 General Social Survey, Cycle 10. A major finding is that those whose mother tongue is English are significantly more likely to return to the parental home than those with French or “other” mother tongues. Other variables include: father's education, number of siblings, gender, age at home‐leaving, and initial reason for home‐leaving. Implications for midlife parental roles and responsibilities, and for family socialization are discussed. 相似文献

The prospects of an intellectual revolution in sociology informed in part by a feminist perspective loomed large in the early
1970s. Following Ward and Grant's (1985) empirical examination of gender and feminist scholarship in sociology journals between
1974 and 1983, our research provides an empirical assessment of the “second ten years” after the feminist critique of the
discipline, 1984–1993. Specifically, we examine the incorporation of gender-content scholarship into mainstream sociology
journals. Our research also assesses the extent to which gender-content scholarship published in these journals is feminist-oriented
or not and the extent to which this is influenced by the sex of authors, the type of journal, and the sex composition of editorships
and editorial boards. Our findings indicate that although there were more gender- and feminist-oriented articles published
in the recent ten-year period, proportionally there were fewer feminist-oriented articles than in the previous ten-year period.
Our findings suggest that a feminist revolution in sociology is not likely to occur anytime soon, although the assimilation
of feminist scholarship into sociology is occurring along the lines of other critical intellectual movements in recent decades.
