[GRASS-user] Linear regression between 2 rasters (old and new)

[António Rocha]

I

I have been using r.series to calculate a linear regression slope for an 
old and new raster map using r.series. But now I need to also obtain the 
error. It seems not to be possible to use r.series. Is this true? if 
yes, what alternative do I have?
THanks
Antonio
