Excuse me if I'm missing something truly basic but...
if I use a power model like this in the kriging system:
1 100 -nst, nugget effect
4 1.2 0.0 0.0 0.0 -it,cc,ang1,ang2,ang3
0.065 0.065 1.0 -a_hmax, a_hmin, a_vert
With a data set in which sampling points are in a regular 10m x 10m grid;
and then I get:
KT3D ESTIMATES WITH: seed
2 161 162 1
Estimate
EstimationVariance
22.844 1.726
22.805 1.722
21.656 1.687
... ...
Is that variance right???
I cannot explain it... I think it is unusually low.
Any comment? Does anyone know if KT3D is handling correctly with power
models?
Thanks,
--
