We consider statistical inference on parameters of a distribution when only pooled data are observed. A moment-based estimating equation approach is proposed to deal with situations where likelihood functions based on pooled data are difficult to work with. We outline the method to obtain estimates and test statistics of the parameters of interest in the general setting. We demonstrate the approach on the family of distributions generated by the Box-Cox transformation model, and, in the process, construct tests for goodness of fit based on the pooled data.  相似文献

At one level, private practice may represent a fairly evolved manifestation of the expanded professional growth and sophistication of the individual social worker who embarks upon this highly individualized proprietary enterprise. However, on a larger scale, this widespread shift toward private practice may indicate a collective disenchantment with agency practice per se and represent a concerted attempt to redefine the fundamental aims and values of social work practice.  相似文献

In this paper a method for the construction of a class of row-column designs with good statistical properties and high efficiency is presented. The class of designs produced is shown to exhibit balance, orthogonality and adjusted orthogonality. The efficiencies of these designs are investigated in detail, and they are shown to be very high, and possibly maximal in some cases.  相似文献

Two potential problems in sex surveys—respondent refusalsand invalid reporting—are examined for national and areaprobability samples of males and females. Little support isfound for the contention that sexual topics constitute a sensitiveresearch area in terms of respondent cooperation and candor.It is found that (1) respondent cooperation, as indicated byrefusals and terminations, is neither more nor less problematicin sex research than in surveys on other topics; (2) respondentreports of sexual matters are not systematically related tointerviewer characteristics such as gender, sexual experience,or technical competence; (3) respondent candor, when self-reported,also is not associated systematically with either interviewercharacteristics or demographic and sexual characteristics ofrespondents. This analysis does identify, however, evidencethat (4) sexual matters often are sensitive topics for interviewersand principal investigators, leading both to interviewer turnoverand the creative construction of unobtrusive data collectionprocedures.  相似文献

Archival data on over 15,000 contributors to 33management journals are used to examine productivitydifferences among scholars in different areas ofmanagement. The results suggest that a fragmentedpublication network offers specialists from different areasdissimilar publication opportunities and experiences,and may contribute to varying levels of publicationproductivity among authors. The implications of our results for future research and facultyevaluation processes are explored.  相似文献

How will sociology fare in the twenty-first century? We love what we do. The problem seems to be in communicating the value of what we do to lay people outside the discipline. Sociology’s future in part will be dependent upon its practitioners demonstrating its utility in the marketplace of everyday life, assessment and decision making. This paper offers a twenty-year perspective of one sociology department’s work in a rural Appalachian region. While providing a brief overview of a series of initiatives, it explains in depth our involvement and contributions to a community-based health project.  相似文献
