[ai-geostats] Re: Frightened of Spatial Autocorrelation
Kevin Sounds like an ideal case for Geographically Weighted Regression. You could use semi-variograms or spatial auto-correlation to determine exactly how proximity defines relationship. My only current beef with GWR is the seemingly pre-defined distance weighting functions. Not had much time to get into this yet, so don't dump on me all you experts out there. I would be interested in any published results on this as one of my business partners is doing similar work on bronze age denmark. Isobel http://uk.geocities.com/drisobelclark ___ALL-NEW Yahoo!

Re: [ai-geostats] Re: Frightened of Spatial Autocorrelation
You might look at the following series of papers: http://www.nceas.ucsb.edu/~liebhold/ecography/ While the papers are written with an ecological focus, settling is settling is settling. Hope they help... Steve Isobel Clark wrote: Kevin Sounds like an ideal case for Geographically Weighted Regression.

Re: [ai-geostats] Re: Frightened of Spatial Autocorrelation
Isobel, Kevin and others I would be very interested as well, since my collegue (an archaeologist) and myself (geographer) are doing work on Bronze Age Denmark, in the landscape of Vendsyssel. See web site http://websrv5.sdu.dk/ejstrud/forskning.html with paper http://websrv5.sdu.dk/ejstrud/forskning/GIS/ejstrud_wunsdorf_2001.pdf and http://www.humaniora.sdu.dk/kulturmiljoe (mostly in Danish) Niels Isobel Clark wrote: Kevin Sounds like an ideal case for Geographically Weighted Regression.
