Many thank`s to everybody for help with this topic (below). Anyway,
could somebody help me with the paper
Approximate analysis of variance of spatially autocorrelated regional data
Legendre et al. (1990) Journal of Classification 7: 53-75
/I /cannot google it out. Besides, I do not have SAS to carry the
analysis. Is there some other way, maybe something in R?
Regards
Tomas
Dear list,
I `d appreciate your help. I have 2000 randomly distributed point data
with spatially autocorrelated attributes. The region is divided into
several zones (seamless). I need to evaluate whether the borders between
neigboring zones are relevant, i.e. whether there is a significant
difference between central values of the attributes in adjacent zones
(ANOVA problem, but samples are not independent). Polygonal declustering
is good to solve under/over sampled locations problem, but this does not
accounts for autocorrelation.
Correlation of spatially autocorrelated data has been discussed many
times, however I cannot find references on something like ANOVA of
autocorrelated data (autocorrelation within groups).
Any help appreciated, maybe also some references to relevant articles.
Thank`s a lot
Regards
Tomas
