Research group Stat4Reg is a research laboratory, where scientists work at developing causal machine learning models, methods and free software for the analysis of large scale databases including population-wide linkages of health and socio-economics registers (record linkage data), brain imaging longitudinal studies, etc.

Causal inference and machine learning: we study how modern machine learning methods can be utilised for causal discovery and inference based on very large databases. The challenges we tackled are theoretical (identification theory, high dimensionality problems, asymptotic theory for inference) and methodological (algorithm capable of handling very large datasets in reasonable computer time; secure computing solutions to be able to handle highly sensitive data).
Missing data and other selection mechanisms: combining registers, surveys and other longitudinal studies yields complex micro-data sets. Studies based on such data must carefully model sample selection and other missing data mechanisms. We develop such models and proposed methods to study deviations from the assumptions made (sensitivity analyses).
Life course studies: Life course studies is an lively field of study in the social and health sciences, where the purpose is to study individual life trajectories. Life trajectories with different social and health domains can nowadays been observed and studied thanks to the availability of rich and large source of micro-data.
Free software: user friendly R functions are developed, making accessible the methods developed to the wider scientific community.
