Hi 

In partially answering my own question about spatial
interpolation model validation, I Read The Fine 
Manual and found 

r.surf.idw -e 

was supposed to give me the drop 1 cross validation
at the data sites.

So, I converted my site data to raster data and ran
it, but it gave a segmentation fault. It runs ok
without the -e. The data range from 1 to 9000.
293 sites.
