[R-sig-Geo] Building a prediction raster when the statistical model was built from sampling units of different sizes

[chris english]

Hi Nell,

Just a couple of questions. Trapping sites range from 24km^2 - 236km^2, and
there are 50 such sites, looking at the 50 sites might there be a way to
bin them reasonably into trap area groups?

Your 50 observations suggests one thing was trapped and thereafter trapping
was discontinued. Is this correct?

And just for general information, what was being trapped?

Sticking closer to your data, you might consider GAM(ing) the bins and
summing the resultant GAMs. Need to think some more on the predictive
raster aspect. Sorry for an essentially inconclusive answer.

Chris
