چکیده
Within the DIECOFIS framework, ec3, the Division of Business Statistics from the Vienna University of Economics and Business Administration and ISTAT worked together to find methods to create a comprehensive database of enterprise data required for taxation microsimulations via integration of existing disparate enterprise data sources. This paper provides an overview of the broad spectrum of investigated methodology (including exact and statistical matching as well as imputation) and related statistical quality indicators, and emphasises the relevance of data integration, especially for official statistics, as a means of using available information more efficiently and improving the quality of a statistical agency’s products. Finally, an outlook on an empirical study comparing different exact matching procedures in the maintenance of Statistics Austria’s Business Register is presented. Zusammenfassung: Im Rahmen von DIECOFIS gab es eine Zusammenarbeit von ec3, der Abteilung für Wirtschaftsstatistik der WU Wien und ISTAT zur Analyse von Datenintegrationsmethoden zur Erstellung einer umfassenden Unternehmensdatenbasis für Steuer-MikroSimulationsstudien durch Verknüpfung bestehender disparater Datenquellen. Dieser Artikel gibt einen Überblick über das breite Spektrum der untersuchten Methoden (v.a. Verfahren des exakten und statistischen Matching, aber auch Imputationstechniken) und relevante statistische Qualitätsindikatoren. Er betont außerdem die Bedeutung der Datenintegration, insbesondere für die amtliche Statistik, als Möglichkeit, vorhandene Daten effizienter zu nützen und die Qualität der Produkte eines öffentlichen Statistikanbieters zu verbessern. Abschließend wird ein Ausblick auf eine empirische Studie zum Vergleich unterschiedlicher exakter Matchingverfahren beim Abgleich des Unternehmensregisters der Bundesanstalt Statistik Österreichs gegeben.

متن کاملIntegration and Reduction of Microarray Gene Expressions Using an Information Theory Approach
The DNA microarray is an important technique that allows researchers to analyze many gene expression data in parallel. Although the data can be more significant if they come out of separate experiments, one of the most challenging phases in the microarray context is the integration of separate expression level datasets that have gathered through different techniques.

متن کاملProper integration time of polarization signals of internetwork regions using Sunrise/IMaX data
Distribution of magnetic fields in the quiet-Sun internetwork areas has been affected by weak polarization (in particular Stokes Q and U) signals. To improve the signal-to-noise ratio (SNR) of the weak polarization signals, several approaches, including temporal integrations, have been proposed in the literature. In this study, we aim to investigate a proper temporal-integration time with which...
متن کاملA Fully Integrated Method for Dynamic Rock Type Characterization Development in One of Iranian Off-Shore Oil Reservoir
Rock selection in modeling and simulation studies is usually based on two techniques; routinely defined rock types and those defined by special core analysis (SCAL). The challenge in utilizing these two techniques is that they are frequently assumed to be the same, but in practice, static rock-types (routinely defined) are not always representative of dynamic rock-types (SCAL defined) in the re...
