The smooth goodness of fit tests are generalized to singly censored data and applied to the problem of testing Weibull (or extreme value) fit. Smooth tests, Pearson-type tests, and the spacings tests proposed by Mann, Schemer, and Fertig (1973) are compared on the basis of local asymptotic relative efficiency with respect to the asymptotic best test against generalized gamma alternatives, The smooth test of order one Is found to be most efficient for the generalized gamma alternatives. 相似文献

Survey data collected from a southwestern metropolitan area indicate that self-defined politically conservative individuals are less inclined to commit criminal or deviant acts than their liberal or moderate counterparts; however, results from multivariate analyses indicate that measures of self-control and pressure to conform all reduce the effects of political conservatism to nonsignificance. In general, the relationship between political ideology and misbehavior appears to be partly spurious and partly indirectly attributable to the effects of other social and situational factors. Moreover, responsiveness to pressures to conform is not due to self-control. The results provide some challenge to traditional interpretations of misbehavior but they also confirm an important part played by structural/contextual variables. 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

A brief survey of censuses previously taken in Northern Nigeria makes clear by comparison the importance of the 1952 Census in the acquisition of demographic data. Some of the problems of organising and conducting the census are considered. The analysis of the census results pays special attention to the pattern of population density but consideration is also given to age and sex structure, occupations, tribal data, literacy and religions. Shortcomings and omissions in the census, particularly the absence of any information on migration, are noted. The conclusion stresses the importance of the 1952 Census as a basis for future demographic studies ; the evidence for an increasing population but the absence of vital statistics to explain this ; the need for much further detailed analysis to be undertaken of the data in the 1952 Census. 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

Representations are obtained for the probabilities that a Strict Borda Paradox and a Strong Borda Paradox are observed for
large electorates with three candidates under the standard assumptions of Impartial Culture and Impartial Anonymous Culture.
These representations are obtained for general weighted scoring rules (WSRs), and the probabilities are found to be maximized
for voting rules like plurality rule and negative plurality rule. It is found that these paradox probabilities are not reduced
for every scoring rule with the introduction of some degree of dependence among voters’ preferences with IAC. It is concluded
that actual observances of a Strict Borda Paradox should be extremely rare, and that while observances of a Strong Borda Paradox
should also be rare, they might occasionally be witnessed. 相似文献

Abstract The most important issue which surrounds attitude theory today is the so called “consistency issue.” It is an issue which focuses on the failure of attitude theory and research to demonstrate the kind of causal relationship between attitudes and behavior which has been traditionally asserted in the logical underpinnings of that theory. For some time, the critics of attitude theory and research have suggested that the inconsistency between attitudes and acts would not be reduced until attitudes were rooted in the social process within which human behavior occurs. This criticism has been responded to by contemporary attitude specialists who have made notable modifications in theory and research to take account of social variables which influence the assumed relationship between attitudes and behavior. However, some of the criticisms of attitude theory have gone beyond pointing out the lack of a “socialized” conception of the problem to attack the logical underpinnings of the entire enterprise. While this paper is not a renewal of these criticisms of attitude theory, it is an attempt to identify and explicate a conception of attitudes which is a true sociological alternative to more traditional psychological conceptions. 相似文献

The effect of a single variable data point, x, on the usual test statistics for traditional hypothesis tests for means is analyzed. It is shown that an outlier may have a profound and unexpected effect on the test statistic. Although it might appear that an outlier would tend to lend support to the alternate hypothesis, it may in fact detract from the significance of the test. In one-population tests and analysis of variance (ANOVA), the value of x that maximizes the significance of the test statistic is given. This value does not have to be unusually large or small. In fact, it often falls within the range of the other sample points. In the general one-population case, the limiting value for the test statistic is shown to be +1. In the case involving more than one population, it is shown that the limiting value of the test statistic is a function only of the number of members in the samples and not their relative values. Special cases are identified in which the test statistic is shown to have unique characteristics depending on the characteristics of the data. 相似文献

ABSTRACT The purposes of this paper are to abstract from a number of articles variance component estimation procedures which can be used for completely random balanced incomplete block designs, to develop an iterated least squares (ITLS) computing algorithm for calculating maximum likelihood estimates, and to compare these procedures by use of simulated experiments. Based on the simulated experiments, the estimated mean square errors of the ITLS estimates are generally less than*those for previously proposed analysis of variance and symmetric sums estimators. 相似文献
