I can think of two reasons, without having looked at anything else than
your message:
1. Range=162 may mean a different thing for the exponential model; for
gstat it means the range parameter as in c1(1-exp(h/a)). This is all
documented. In ArcGIS it might mean something like c1(1-exp(h/(3a)); f
Hi Edzer,
I found a problem with gstat "krige" prediction if I am correct this
time. For example, with OLSENP variable in my dataset, I developed a
theoretical model for log(OLSENP) variogram: model=exp, c0=0.2019,
c1=0.2218 and Range=162 meters. By using this model, I predicted the
OLSENP surface
