Keynote speakers

Ph.D., Associate professor of statistics,  Shu Yang (North Carolina State University, USA)

Shu Yang is an associate professor of Statistics at NC State University. She received her Ph.D. in Applied Mathematics and Statistics from Iowa State University and postdoctoral training at Harvard T.H. Chan School of Public Health. Her primary research interest is causal inference and data integration, particularly with applications to comparative effectiveness research in health studies. She also works extensively on methods for missing data, spatial statistics, and sampling statistics. She has been Principal Investigator for several U.S. National Science Foundation and National Institute of Health research projects. 

Data integration: a new paradigm  for survey statisticsFinite population inference is a central goal in survey sampling. Probability sampling is the gold standard statistical approach to finite population inference. Challenges arise due to high costs and increasing non-response rates. Data integration provides a timely solution by leveraging multiple data sources to provide more robust and efficient inference than using any single data source alone. The technique for data integration varies depending on the types of samples and available information to be combined. This talk provides a systematic review of data integration techniques for combining probability and non-probability samples and for combining probability and big data samples. A wide range of integration methods will be covered such as calibration weighting, inverse probability weighting, mass imputation, and doubly robust methods. Finally, I will highlight important questions for future research.

Prof. Dr.  Piet Daas (Eindhoven University of Technology & Statistics Netherlands) 

Prof. Dr. Piet Daas is a senior-methodologist at Statistics Netherlands where he leads the research on Big Data. He is a professor by  special appointment on ‘Big Data in Official Statistics’ at the Eindhoven University of Technology where his work focuses on the development of Big Data methodology. Piet teaches Big Data (on-line) at Statistics Netherlands, the University of Utrecht, University of Maryland, and the University of Mannheim.

Identifying different types of companies via their website text

The internet and especially web pages are a very interesting source of data. It has very interesting potential applications such as providing novel insights on the activities of companies, to inform policy makers and also for official statistics, especially when performed at large scale. However, extracting relevant and reliable information from big data sources in a reproducible way is not an easy task. In this presentation results of Machine Learning based classifications of web sites texts are discussed in relation to the identification of innovative, platform economy and AI companies.

Associate Professor,  Deputy Director Marcin Szymkowiak, (Department of Statistics, Poznan University of Economics and Business;  Statistical Office in Poznan)

Associate Professor at Department of Statistics, Poznan University of Economics and Business and  Deputy Director at Statistical Office in Poznan, with many years of experience in the field of statistical data analysis. He specializes in small area estimation, methods of dealing with nonresponse (imputation and calibration), survey sampling, statistical methods of data integration (probabilistic record linking, statistical matching), and multivariate data analysis. He has participated in many domestic and international projects in cooperation with the Central Statistical Office in Poland, the World Bank and Eurostat (for instance Eurarea, ESSnet on Small Area Estimation, MEETS, ESSnet on Data Integration, VIP Admin, Memobust, Improvement of EU censuses quality from 2021, Foreigners in the Polish regional labour market, Extension of the Labour Force Survey indicators of labour market and education).

Small area estimation in official statistics - past, present and future directions of applications

Small area estimation methodology (SAE) has been developed to produce reliable estimates of different characteristics of interest, such as means, counts, quantiles or ratios for domains for which only small samples are available. From that point of view SAE has become a topic of great importance due to the growing demand for reliable small area statistics. SAE methodology is used by different national statistical institutes in different areas, in particular to estimate quantities that are related to the labour market, agriculture or business statistics. It is also useful for mapping poverty. For instance, the World Bank has used SAE methodology to prepare poverty maps for tens countries all over the world. The main purpose of this presentation is to provide a review of the main applications in SAE methods, mainly in official statistics. Presentation will be based on earlier and present applications which serve as a necessary background for the new directions of the SAE development, including using big data sources as an example.
