Hi,
Is it correct that the time it takes to run r.regression.multi depends
on the region settings (i.e., total number of raster cells in the
region), and is not influenced by the number of NULL values in the raster?
I am asking because I though I could speed up calculations when masking
out part area (using a mask based on x random points), but perhaps that
doesn't make sense?
Cheers
Paulo
