Biography

Johan Lyhagen is a full Professor of Statistics at Uppsala University since 2010, specializing in time series econometrics. His primary research focus is on time series econometrics, where he regularly explores various research areas. He has extensive experience in supervising PhD students and engaging in academic administration, having served as head of the department and as a member of the faculty board committee for the recruitment of professors. From a statistical perspective, he investigates economic equilibriums modeled through linear relations, specifically cointegrated relationships. His work includes examining the existence of equilibriums between economic variables and assessing how these can be estimated. Recently, his research interests have expanded to analyze short-term dynamics within business cycles, particularly how changes in interest rates can affect economic conditions during booms and recessions. Additionally, he has engaged in topics such as psychometrics, including non-linear structural equation models and robust inference, optimal bins for histograms, and problems related to measurement errors.
