Isolating Spatial Autocorrelation, Aggregation Bias, and Distributional Violations in Ecological Inference: Comment on Anselin and Cho
Few better ways of checking and improving statistical methods exist than having other researchers go over your results, and so I especially appreciate the efforts in Anselin and Cho (2002), hereinafter AC. In this note, I make two main points. First, AC’s numerical findings from its empirical example and simulations contradict no prior research. The article’s one empirical example violates EI’s...
متن کاملSpatial autocorrelation of ecological phenomena.
Ecological variables often fluctuate synchronously over wide geographical areas, a phenomenon known as spatial autocorrelation or spatial synchrony. Development of statistical approaches designed to test for spatial autocorrelation combined with the increasing accessibility of long-term, large-scale ecological datasets are now making it possible to document the patterns and understand the cause...
متن کاملSpatial Effects and Ecological Inference
This paper examines the role of spatial effects in ecological inference. Both formally and through simulation experiments, we consider the problems associated with ecological inference and cross-level inference methods in the presence of increasing degrees of spatial autocorrelation. Past assessments of spatial autocorrelation in aggregate data analysis focused on unidimensional, one-directiona...

متن کاملResponse to Comment on ‘‘Methods to account for spatial autocorrelation in the analysis of species distributional data: a review’’
I was amused to read, in a criticism of another publication, that the criticised authors did not adhere to the ‘‘principles of ecological niche modelling’’ (McNyset and Blackburn 2006, p. 782). There aren’t any such ‘‘principles’’. Ecological niche modelling really is statistics on species distribution data. All methods employed need to be statistically consistent, i.e. meet the assumptions mad...
