Many National Statistical Institutes (NSIs), especially in Europe, are moving from single-source statistics to multi-source statistics. By combining data sources, NSIs can produce more detailed and more timely statistics and respond more quickly to events in society. By combining survey data with already available administrative data and Big Data, NSIs can save data collection and processing costs and reduce the burden on respondents. However, multi-source statistics come with new problems that need to be overcome before the resulting output quality is sufficiently high and before those statistics can be produced efficiently. What complicates the production of multi-source statistics is that they come in many different varieties as data sets can be combined in many different ways. Given the rapidly increasing importance of producing multi-source statistics in Official Statistics, there has been considerable research activity in this area over the last few years, and some frameworks have been developed for multi-source statistics. Useful as these frameworks are, they generally do not give guidelines to which method could be applied in a certain situation arising in practice. In this paper, we aim to fill that gap, structure the world of multi-source statistics and its problems and provide some guidance to suitable methods for these problems. 相似文献

This article presents the results of an empirical investigation of project management practice. Practice is investigated through the study of the extent of use of a large number of practices, tools, and techniques specific to project management. A sample of 2,339 practitioners participating in a large‐scale international survey is used for this article. The sample size and the diversity of contexts in which the respondents are working render the analysis feasible and the results reliable. The data is analyzed to identify patterns of practice. More specifically, using principal component analysis, the research identifies patterns that demonstrate that practitioners use project management tools and techniques in groups or “toolsets.” A brief attempt is made to compare results with A Guide to the Project Management Body of Knowledge (PMBOK® Guide) (PMI, 2008 ) Knowledge Areas and Process Groups. The article also shows how practice varies with the management of different types of projects: engineering and construction; business and financial services; information technology (IT) and telecommunications; and software development projects. The identification of these variations has important consequences for practice and for the study of practice. 相似文献

Opening up open-ended survey data using qualitative software 总被引:1,自引:0,他引:1
This article considers the contribution that qualitative software can make to ‘opening up’ open-ended question (‘OEQ’) data from surveys. While integrating OEQ data with the analysis of fixed response items is a challenge, it is also an endeavour for which qualitative software offers considerable support. For survey researchers who wish to derive more analytic value from OEQ data, qualitative software can be a useful resource. We profile the systematic use of qualitative software for such purposes, and the procedures and practical considerations involved. The discussion is illustrated by examples derived from a survey dataset relating to environmental risk in the UK. 相似文献
