After "Raising the Bar'': applied maximum likelihood estimation of families of models in spatial econometrics.
Bivand, Roger S. (Journal article; Peer reviewed, 2012)Elhorst (2010) shows how the recent publication of LeSage and Pace (2009) in his expression “raises the bar” for our fitting of spatial econometrics models. By extending the family of models that deserve attention, Elhorst ... -
After “Raising the Bar”: applied maximum likelihood estimation of families of models in spatial econometrics
Bivand, Roger S. (Discussion Papers;22/2011, Working paper, 2011-11)Elhorst (2010) shows how the recent publication of LeSage and Pace (2009) in his expression “raises the bar” for our fitting of spatial econometrics models. By extending the family of models that deserve attention, Elhorst ... -
Comparing estimation methods for spatial econometrics techniques using R
Bivand, Roger S. (Discussion paper, Working paper, 2010-10)Recent advances in spatial econometrics model fitting techniques have made it more desirable to be able to compare results and timings. Results should correspond between implementations using different applications, ... -
Computing the Jacobian in spatial models : an applied survey
Bivand, Roger S. (Discussion paper, Working paper, 2010-08)Despite attempts to get around the Jacobian in fitting spatial econometric models by using GMM and other approximations, it remains a central problem for maximum likelihood estimation. In principle, and for smaller data ... -
Exploiting parallelization in spatial statistics: an applied survey using R
Bivand, Roger S. (Discussion paper, Working paper, 2010-10)Computing tasks may be parallelized top-down by splitting into per-node chunks when the tasks permit this kind of division, and particularly when there is little or no need for communication between the nodes. Another ... -
Geocomputation and open source software:components and software stacks
Bivand, Roger S. (Discussion Papers;23/2011, Working paper, 2011-11)Geocomputation, with its necessary focus on software development and methods innovation, has enjoyed a close relationship with free and open source software communities. These extend from communities providing the ... -
Progress in the R ecosystem for representing and handling spatial data
Bivand, Roger S. (Peer reviewed; Journal article, 2020)Twenty years have passed since Bivand and Gebhardt (J Geogr Syst 2(3):307–317, 2000. https://doi.org/10.1007/PL00011460) indicated that there was a good match between the then nascent open-source R programming language ... -
Regional growth in Western Europe : an empirical exploration of interactions with agriculture and agricultural policy
Bivand, Roger S.; Brunstad, Rolf Jens (Discussion paper, Working paper, 2002-01)Studies of convergence of regional growth in Western Europe have given varying results, depending on the addition of conditioning variables and estimation methods, as well as underlying models. This exploration adds ... -
Regional growth in Western Europe : detecting spatial misspecification using the R environment
Bivand, Roger S.; Brunstad, Rolf Jens (Discussion paper, Working paper, 2006-01)The work discussed in Bivand and Brunstad (2003) was an attempt to throw light on apparent variability in regional convergence in relation to agriculture as a sector subject to powerful political measures, in Western ...
