Slovene statistician
Aleš Žiberna is a
Slovene
statistician , whose specialty is
network analysis . His specific research interests include
blockmodeling ,
multivariate analysis and
computer intensive methods (e.g.,
computer simulations ,
resampling methods ).
[1]
Currently, he is employed at the
Faculty of Social Sciences of the
University of Ljubljana , specifically at the Chair of Social Informatics and Methodology,
[2] and Centre for Methodology and Informatics.
[3]
Work
In 2007, he proposed a solution to the
generalized valued blockmodeling by introducing
homogeneity blockmodeling with the basic idea "that the inconsistency of an empirical block with its ideal block can be measured by within block variability of appropriate values". The newly-formed ideal blocks, which are appropriate for blockmodeling of valued networks, are then presented together with the definitions of their block inconsistencies.
[4]
He also (in 2007/08) developed an
implicit blockmodeling approach, based on previous work of
Batagelj and
Ferligoj (2000).
[5] : 16–17
[6]
[7]
In 2014, he proposed a new approach to the
blockmodeling -
blockmodeling linked networks .
