Research
interests
All my
research has been devoted to Graphical Markov Models. The class of Graphical
Markov Models is so vast that includes many existing models, like Structural
Equation Models, log-linear models, and so on, that I never get tired in
exploring them from the theoretical point of view and in using them in applied
data analysis.
From the
theoretical point of view I have been attracted by issues of identification and
distortion induced by unobserved factors. For that I have also received a grant
from the American Institute of Mathematics AIM
('SQuaRE' grant: 2011-2013).
Papers that address the identification issues are e.g. 6, 7, 9, 10, 14, 24 of the
paper list below. Papers that address issue of distortion are e.g. 1, 2, 5,
11, 17. In many applied research I have been using Graphical Models with latent
variables: see papers 5, 6, 16, 23 or the book chapter 2 on
capture-recapture estimation.
Currently,
I am a member of SIMSAM, Interdisciplinary research group on early life exposure and
health: A registry-based life-course
perspective with modern epidemiological and statistical approches, at Umeå
University.
Further
Research Interests include Credit Scoring see e.g.
paper 8 or 13, and book 5.
