Econometric research has a long tradition in the University of Helsinki
initiated by the first Professor of Statistics Leo Törnqvist.
Since the 1990s modern methods of modelling nonstationary trending time
series has been the focus of the Research Group of Econometrics. Recent
research is also concerned with analysis of nonlinear time
series analysis relevant e.g. in the analysis of financial time series.

The group was closely connected with the Research Unit of Economic
) as long
as it existed. RUESG was a centre of
excellence in research for the years 2002-2007.
