Bayesian networks for imputation 总被引:1,自引:0,他引:1

Summary. Bayesian networks are particularly useful for dealing with high dimensional statistical problems. They allow a reduction in the complexity of the phenomenon under study by representing joint relationships between a set of variables through conditional relationships between subsets of these variables. Following Thibaudeau and Winkler we use Bayesian networks for imputing missing values. This method is introduced to deal with the problem of the consistency of imputed values: preservation of statistical relationships between variables ( statistical consistency ) and preservation of logical constraints in data ( logical consistency ). We perform some experiments on a subset of anonymous individual records from the 1991 UK population census. 相似文献

Major policy changes like the 1986 Tax Reform Act (TRA) in the United States provide natural experiments to study attitudinal and behavior responses to law. Surprisingly, public evaluations of the TRA became increasingly negative after passage, while general support for the tax system became more positive in response to the changes. To explain this puzzle, we propose a dynamic model of taxpayer attitudes that is consistent with the observed loose linkage between logically-connected concepts. We briefly review the political context, objectives and impacts of the 1986 Tax Reform Act, and present several studies testing the impact of self-interest, prior beliefs, and social discussion on changes in attitudes and behavior.Results suggest that the complexity of taxes and difficulty in knowing objective impacts weakens the role of self-interest in attitudinal changes, thereby strengthening the role of prior beliefs and discussion. Evaluations of tax laws are most responsive to more politically-oriented influences. 相似文献

In this article we provide a rigorous treatment of one of the central statistical issues of credit risk management. GivenK-1 rating categories, the rating of a corporate bond over a certain horizon may either stay the same or change to one of the
remainingK-2 categories; in addition, it is usually the case that the rating of some bonds is withdrawn during the time interval considered
in the analysis. When estimating transition probabilities, we have thus to consider aK-th category, called withdrawal, which contains (partially) missing data. We show how maximum likelihood estimation can be
performed in this setup; whereas in discrete time our solution gives rigorous support to a solution often used in applications,
in continuous time the maximum likelihood estimator of the transition matrix computed by means of the EM algorithm represents
a significant improvement over existing methods. 相似文献

Zusammenfassung Der Beitrag beschreibt Planung, Verlauf und abschlie?ende Beurteilung eines gruppendynamischen Seminars, in dem für angehende
Supervisorinnen und Supervisoren das Thema Organisations-Entwicklung dargestellt und vermittelt werden sollte. Ausgangspunkt
war die Kl?rung des Inhaltsraums von Organisations-Entwicklung als geplantem sozialen Wandel, der auf sozialwissenschaftlicher
Grundlage zielgerichtet, strategisch und mit Zeitperspektive in der Zusammenarbeit zwischen externer und interner Sach-, Prozess-
und Entscheidungskompetenz durchgeführt wird. Als Ziele des Seminars wurden festgelegt, Organisations-Entwicklung als sozialwissenschaftliches
Instrument zu begründen, Organisations-Entwicklung-Schritte zu konzipieren und sie kollegial zu kommunizieren. Darüber hinaus
wurden Qualit?tskriterien für das Seminar formuliert: Praxisn?he, Kl?rung des Inhaltsraum Selbstorganisation, Selbststeuerung,
Ressourcenaktivierung, Konfliktregulierung, Analyse des Gruppenprozesses, Nutzung von Feldkompetenz und Verhaltensmodellen,
Etablierung von Feedbackschleifen, Koordination und Synergie, kollegialer Austausch und Kl?rung pers?nlicher Organisations-Entwicklungs-Fragen.
Bausteine und Lernorte des Seminars waren das Plenum, die Lernpartnerschaft, das OE-Team, die Beobachterfunktion, die Tagesreflexion,
die Sitzung Frage und Antwort, die Darstellung von Praxisf?llen, das Plenum-Feinsteuerung, die Analyse der Arbeitsprozesse
des OE-Teams sowie Transfer und Auswertung. Der tats?chliche Verlauf des Seminars wird aus der Perspektive des Leiters kommentiert.
Anhand von Verlaufsbeobachtungen und Teilnehmer?u?erungen wird der Eindruck begründet, dass diese Form des Vorgehens als lernintensiv,
autonomief?rdernd und für die zu erwerbende Supervisionskompetenz als praxisrelevant betrachtet werden kann.

This article describes the plantification, progress and final evaluation of a group-dynamic seminar for future supervisors in which the topic organization development was presented and introduced. The content of organization development was first defined as a planned social change which is executed based on social sciences in a goal-oriented, strategic way which considers the time perspective of the cooperation between external and internal specialised-, process- and decision competence. Goals of the seminar were to justify that organisation development is a social science tool, to plan organization development steps and to communicate them to peer seminar participants. Further more, the following quality criteria for the seminar were formulated: practice orientation, definition of self-organisation content, self regulation, resources activation, conflict regulation, group process analysis, field competence and behaviour models usage, feedback establishment, coordination and synergy, mutual peer exchange and finding answers to personal questions about organization development. The building blocks and learn places of the seminar were the plenary sessions, the learning partnership, the od-teams, the observer function, the day analysis, the questions and answers session, the case study presentation, the analysis of the work processes as well as transfer and evaluation. The progression of the seminar is commented from the point of view of the seminar leader. Progress observations and participant’s feedback justify the impression that this way to conceptualise provides an intensive learning experience, supports autonomy and provides relevant and practical supervision competence.

The authors consider Bayesian analysis for continuous‐time Markov chain models based on a conditional reference prior. For such models, inference of the elapsed time between chain observations depends heavily on the rate of decay of the prior as the elapsed time increases. Moreover, improper priors on the elapsed time may lead to improper posterior distributions. In addition, an infinitesimal rate matrix also characterizes this class of models. Experts often have good prior knowledge about the parameters of this matrix. The authors show that the use of a proper prior for the rate matrix parameters together with the conditional reference prior for the elapsed time yields a proper posterior distribution. The authors also demonstrate that, when compared to analyses based on priors previously proposed in the literature, a Bayesian analysis on the elapsed time based on the conditional reference prior possesses better frequentist properties. The type of prior thus represents a better default prior choice for estimation software. 相似文献
