He considers his most significant achievement to date as having people use improved statistical methods to study children in educational settings and seeing research improve as a result. He has spent the last 10 years focusing on building into statistical models the fact that children are clustered into social settings rather than as solitary individuals. In addition, he has also presented workshops at national meetings to enable people to understand these methods.

Dag Sörbom teaches statistics at the University of Uppsala. His research interests include: covariance structure analysis and structural equation models, especially multiple-group problems. Together with Professor Karl Jöreskog, he developed the LISREL computer program.
