The EU funded project involved the documentation of available data sources relative to their consistency with TSA-concepts, identification of data gaps, and recommendations for improvements. From establishing the TSA-Tables, total expenditures of inbound, domestic, outbound and internal tourism as well as their structure by consumption categories are defined, which constitutes the first step to measure the impact triggered by tourism demand. The results show how crucial it is for tourism analysis to properly measure all components included in tourism consumption, and to separately treat overnight from same-day visitors, parameters which are not yet considered in current practice of Greek tourism statistics.

Data integration is also of major interest for official statistics agencies as a means of using available information more efficiently and improving the quality of the agency's products. The Austrian member of the project consortium comprises university departments, representatives from the Bundesanstalt Statistik Austria, from the Statistical Department of the Austrian Economic Chamber, and from ec3, a non-profit research corporation. This paper gives a short report on DIECOFIS in general and on the Austrian contribution to the project, mainly dealing with data integration methodology. Various papers that have been read at the DIECOFIS workshop last November in Vienna, will be published as a Special Issue of the Austrian Journal of Statistics. Zusammenfassung: Techniken der Integration von Datenbeständen sind eines der Kernthemen von DIECOFIS, ein EU-finanziertes, internationales Forschungsprojekt mit der Zielsetzung, Methoden für die Konstruktion eines Systems von Indikatoren der Wettbewerbsfähigkeit und der steuerlichen Auswirkungen auf die Unternehmensleistung zu entwickeln. Die Integration von Datenbeständen ist heute von größtem Interesse für die Amtliche Statistik, da diese Techniken es ermöglichen, die verfügbaren Daten effizienter zu nützen und die Qualität der statistischen Produkte zu verbessern. Das österreichische Mitglied des Projektkonsortiums umfasst Universitätsinstitute, Repräsentanten der Bundesanstalt Statistik Österreich, der statistischen Abteilung der Wirtschaftskammer Österreich und des ec3, eines gemeinnützigen Forschungsinstituts. Dieser Artikel berichtet allgemein über DIECOFIS und über den österreichischen Beitrag zum Projekt, der vor allem mit der Integration von Datenbeständen befasst ist. In einem kommenden "Special Issue" der Österreichischen Zeitschrift für Statistik werden die Beiträge publiziert werden, die Mitte November beim DIECOFIS Workshop in Wien vorgetragen wurden.

Estimation procedures and optimal designs for estimation of the individual parameters and of the ... more Estimation procedures and optimal designs for estimation of the individual parameters and of the global parameters are discussed under various conditions of prior knowledge. The extension to nonlinear parametrization of the response function ís based on the asymptotical validity of the results for the linear parametrization. For the case where the error variance and the dispersion matrix are unknown, an iterative estimation procedure is suggested. An example based on dental plaque pH profiles demonstrates the improvement that is achieved (a) through using the optimal design or a design that ís close to the optimal, and (b) through taking into account prior information.

If the critical limits of the individual tests are allowed to depend on the sample size in an appropriate way, the test procedure provides a weakly consistent estimate of the minimal 'correct5 subset of the model parameters
