Summary of Course:

More and more, social science research makes use of data residing in multiple sources, including sample surveys, census and administrative registers. A major benefit is widened scope of analysis that could not have been feasible based on the data from each source on its own. However, the combined data may contain many apparent inconsistencies and shortcomings that one needs to overcome. The data linkage and integration process may also generate errors of its own. To analyse such imperfect data as-is leads generally to incorrect inference.

Day one provides a general introduction to combining multiple administrative and survey datasets for statistical purposes. A total-error framework is presented for integrated statistical data, which provides a systematic overview of the origin and nature of the various potential errors. The most typical data configurations are illustrated and the relevant statistical methods reviewed.

Day two covers a handful of selected statistical methods. Training will be given on the techniques of data fusion, or statistical matching, by which joint statistical data is created from separate marginal observations. The participants will be introduced to several imputation or adjustment techniques, in the presence of constraints arising from overlapping data sources.

Course Contents:

  • Life-cycle of integrated statistical data and transformation processes
  • A framework of error sources associated with data integration
  • Population coverage and unit errors
  • Uncertainty and techniques of categorical data fusion, or statistical matching
  • Imputation and adjustment methods subjected to micro- and macro-level constraint

 

By the end of the course participants will have:

  • Understanding of potential errors and statistical uncertainty involved in data integration
  • Ability to apply relevant concepts and methods in practice
  • Appreciation of opportunities and challenges of inference based on data integration

 

Computer Software and Computer workshops:

This event includes computer workshops. (Please provide further detail such as what types of software needed):

The course will involve practice/exercise using R at https://www.r-project.org/

 

Presenter:

Li-Chun Zhang is Professor of Social Statistics at the Southampton Statistical Sciences Research Institute (S3RI) at the University of Southampton, and senior methodologist at Statistics Norway. He has participated in a number of EU framework projects and Eurostat ESSnet projects. His research interest includes data integration, statistical uses of administrative sources, sampling, sample coordination, estimation and imputation, treatment of non-sampling errors, small area estimation, statistical data editing, and statistical modelling. He obtained Dr. Scient. in Statistics at the University of Tromsø, Norway.

 

Target Audience:

Social and medical researchers with interests in combining data from multiple sources or analysing data from different sources; staff at National Statistical Institutes (or similar organisations) who are involved in the design, management and quality assurance of statistical processes based on data from multiple sources including censuses, administrative data and sample surveys. Methodological training, knowledge and experience will be helpful.

 

Pre-requisites:

Understanding of central concepts of statistical uncertainty (such as bias, variance, confidence interval) and distribution, basic knowledge of data cleaning and imputation, basic experience/skill of R for statistical computing
