In this note, we consider the problem of the existence of adaptive confidence bands in the fixed design regression model, adapting ideas in Hoffmann and Nickl [(2011), ‘On Adaptive Inference and Confidence Bands’, Annals of Statistics, 39, 2383–2409] to the present case. In the course of the proof, we show that sup-norm adaptive estimators exist as well in the regression setting. 相似文献

We examined factors related to attitudes toward marriage and the importance of having children in both the US and Singapore.
Path analysis indicated that life dissatisfaction leads to materialism, and both of these factors lead to favorable attitudes
toward marriage, which leads to greater desire for children. Further analysis indicated this model was effective in explaining
the difference in desire for children between Singaporeans and Americans, whereby Singaporeans have lower life satisfaction,
higher materialism, and lower attitudes toward marriage and children. Materialistic standards of success were also related
to the emphasis women placed on potential marriage partners’ earning capacity. As Singaporean women had higher materialistic
standards, they also placed higher emphasis on potential mates’ earning capacity. Results suggest a consideration of psychological
variables such as life satisfaction, materialism, and mate preferences may lead to a better understanding of larger-scale
socioeconomic issues, including low fertility rates among developed East Asian countries. 相似文献

This note examines an augmented cost-of-living index (ACOLI) for the purpose of accounting for “augmented consumption” in real-income measures. Well-being includes not only conventional consumer purchases but also goods and services provided by employers, by mandated social regulations, and by tax-financed public goods. Because augmented consumption is often provided in ways that raise prices but not market incomes, deflating with conventional price indexes may understate real income growth. An exploratory application of the ACOLI approach to the United States during the 1960–1997 period suggests that the Consumer Price Index has grown about 19% faster than the ACOLI. This correction would reduce the estimated cost-of-living increase by .47% per year over the last 37 years. 相似文献

A set of Fortran-77 subroutines is described which compute a nonparametric density estimator expressed as a Fourier series. In addition, a subroutine is given for the estimation of a cumulative distribution. Performance measures are given based on samples from a Weibull distribution. Due to small size and modest space demands, these subroutines are easily implemented on most small computers. 相似文献

This paper provides a fortran algorithm that can be used to compute the cdf of the product of two normal distribution random variables. We also give references that provide mathematical properties, tables, and applications of this distribution 相似文献

Addressing the needs and respecting the rights of internallydisplaced persons (IDPs) is not only a humanitarian and humanrights issue, but also a strategic one affecting both internationalpeace and security and the prospects for sustainable development.This article explores the conceptual linkages between internaldisplacement and peacebuilding, focusing on the ways in whichaddressing the concerns and needs of IDPs can contribute tosustainable peace. The second half of the article looks at institutionalresponses to the challenge of integrating internal displacementinto peacebuilding, with a particular focus on the potentialrole of the new UN Peacebuilding Commission (PBC). 相似文献

Abstract The authors report on the effects of a university and community coalition in preventing problems related to college students' off-campus drinking. The Albany, New York, Committee on University and Community Relations used strategies based on an environmental-management approach that focuses on changing the environment in which individuals make decisions about alcohol consumption and related behaviors. Committee initiatives included improving enforcement of local laws and ordinances, creating a safety-awareness campaign for off-campus students, and developing a comprehensive advertising and beverage-service agreement with local tavern owners. The initiatives were associated with a decline in the number of alcohol-related problems in the community, as indicated by decreases in the number of off-campus noise ordinance reports filed by police and the number of calls to a university-maintained hotline for reporting off-campus problems. An environmental management approach, the authors suggest, has promise as an effective means of preventing alcohol-related problems among college students. 相似文献

For four variables x1,x2, x3 and x4, which have a quadrivariate normal distribution with means equal to zero, the positive ortrhant probability is the probability that all of the x.'s are simultaneously positive. A representation for the quadrivariate normal positive orthant probability is obtained and it is a function of no more than three integrals over a single variable. Extensive testing has shown this representation to be very efficient on a computational basis. 相似文献

A framework for time varying parameter regression models is developed and employed in modeling and forecasting price expectations, using the Livingston data. Alternative model formulations, which include various choices for both the stochastic processes generating the varying parameters and the sets of explanatory variables, are examined and compared by using this framework. These models, some of which have appeared elsewhere and some of which are new, are estimated and used to assess the expectations formation process. 相似文献

Purpose: Many students who are lesbian, gay, bisexual, transgender, or queer (LGBTQ) face hostile school environments that can negatively impact their mental health and education. This study involved a photovoice project where high school students from a gay-straight alliance in the rural southeastern United States took photographs that depicted the issues LGBTQ students were facing and then exhibited their photographs and stories to individuals from the school system and local community to promote awareness, dialogue, and action. Methods: Twenty adults who attended the photovoice exhibit responded to an online survey about their experiences with the intervention. Results: Eighty-five percent of adults reported that the intervention made them think about issues they had not previously considered, including the struggles LGBTQ youths face, gender issues, and living in a rural community. Common emotions experienced at the intervention included feeling excited, concern for the youths, and proud of the youths. Furthermore, 81% of the adults indicated that they would take action or behave differently as a result of the intervention, including supporting and affirming LGBTQ students, using gender-neutral and -inclusive language, and confronting bias in themselves and others. Conclusions: Photovoice is a promising strategy for LGBTQ students to activate adult allies in their community. 相似文献
