Statistical confidentiality : principles and practice by George T Duncan( )

15 editions published between 2011 and 2014 in English and held by 479 WorldCat member libraries worldwide

The eight chapters lay out the dilemma of data stewardship organizations (such as statistical agencies) in resolving the tension between protecting data from snoopers while providing data to legitimate users, explain disclosure risk and explore the types of attack that a data snooper might mount, present the methods of disclosure risk assessment, give techniques for statistical disclosure limitation of both tabular data and microdata, identify measures of the impact of disclosure limitation on data utility, provide restricted access methods as administrative procedures for disclosure control, and finally explore the future of statistical confidentiality. George T. Duncan is Professor of Statistics, Emeritus, Carnegie Mellon University. He chaired the National Academy of Sciences Panel on Confidentiality and Data Access

Improving Access to Data While Protecting Confidentiality Prospects for the Future by George T Duncan( Book )

2 editions published in 1989 in English and held by 3 WorldCat member libraries worldwide

Providing researchers, especially those in the social sciences, with access to publicly collected microdata furthers research while advancing public policy goals in a democratic society. However, while technological improvements have eased remote access to these databases and enabled computer using researchers to perform sophisticated statistical analyses, they have also increased the likelihood that individual records can be re-identified. Government agencies that sponsor the collection of microdata files containing personal and sensitive data are under increased pressure to form policies that allow continued improvements in data access while protecting subject confidentiality. Based on recent developments, this paper reflects on what the near future holds for the resolution of this issue in five arenas: statistical, computer, legal, administrative, and ethical. In the statistical arena, agencies will develop methods of masking data through disclosure limiting and linear affine masking approaches. Electronic gatekeepers and monitors for remote access will be applied in the computer arena. Legal involvement will include legislation that ensures research access and provides sanctions for improper data use. In the administrative arena, agencies will place more responsibility on researchers as data stewards. Finally, ethical concerns will be addressed by developing a researcher's code of conduct.

Electroless plating of bronze by George T Duncan( )

2 editions published in 1983 in English and held by 2 WorldCat member libraries worldwide

A plating bath for the electroless plating of copper and tin (bronze) was developed and by the varying of several parameters such as temperature, concentration copper, tin, dirnethylamine borane (DMAB), and EDTA, the utility of the bath was examined. It was found that DMAB provided a very high plating rate as compared to standard industrial baths consisting of formaldehyde as a reducing agent. Results indicate that the concentration of tin in the plate can be adjusted from 1.5% to 20% with the variation of copper concentration in the bath alone. Adjustment of other factors provided enhancement of plating rates along with small variations in the percentage of tin in the plate. Further, a novel methodology for the analysis of copper and tin simultanously by atomic absorption spectrophotometry was developed using a air-acetylene-oxygen flame. This provided an analysis of tin which was virtually unaffected by any concentration of copper or iron in a solution to be analysed

Stochastic Models of the Distribution of Dyadic Warfare in Time( Book )

1 edition published in 1976 in English and held by 1 WorldCat member library worldwide

Stochastic models are constructed to illuminate the dynamic incidence of international warfare during the 1816-1965 period. It is argued that the probabilistic structure is revealed most clearly through an analysis based on dyads of nations, thereby dissassembling such large wars as World War II. The conceptual focus is maintained on a clear delineation of heterogeneity over time and over actors and of contagion in both its addictive and infectious varieties. Departures from randomness are considered as modifications of the Poisson process. Methodological attention is directed at statistical analysis of the interarrival times between initiations of dyadic warfare. Cyclic behavior is investigated through a cosine wave-form variant of the Poisson process. A conclusion of infectious behavior is supported by a variety of analyses. An autoregressive model of order 4 is found to adequately fit the interarrival times and account for the infectious behavior. (Author)

Bayesian Statistical Estimation in the Finite State Markov Renewal Process( Book )

1 edition published in 1977 in English and held by 1 WorldCat member library worldwide

This paper develops Bayesian statistical estimation procedures for the finite state Markov renewal process. The general case is treated where uncertainty exists about both the waiting time distributions and the transition probabilities. This work extends the Bayesian results of Martin, who only considers the Markov chain case, and Brock, who assumes that the waiting time distributions are known. Moore and Pyke deal only with classical estimation methods. The sampling schemes considered are either to observe n transitions and their associated waiting times, or, more generally, to observe the process for some time T, where T is not necessarily a transition time
