WebNov 11, 2014 · Steffen L. Lauritzen is an internationally highly recognized statistician who has made profound contributions to a broad range of areas in statistical science. He is one of the leading experts in the world on graphical models, a very active research field at the boundary between statistics and computer science. WebGraphical models are among the most common ap-proaches to modeling dependencies in multivariate data (Lauritzen, 1996; Koller and Friedman, 2009). They are a foundational object of study in statistics and machine learning, and have found a variety of applications in causal inference, medicine, nance, dis-tributed systems, and climate science.
