[R-sig-Geo] Universal Block Kriging covariate definition for krige in gstat

2016-01-13 Thread Antonio Manuel Moreno Ródenas
Hello, I would like to rise a question on the use of predict {gstat}, I'm trying to perform the estimation of a spatially distributed variable at the support scale of a particular area (Block kriging). I have access to an additional variable, it is known that the variable of interest is correlated

Thanks a lot Edzer, I'm not sure that would work. In that way I would transfer to the kriging function the averaged value of the covariate in the block. I'm not sure that would make the kriging behave correctly. All the points calculated with the prediction inside the block (and later averaged to
