Dear all,
I'm looking for papers investigating the sensitivity of automatic variogram
fitting functions to outliers. I'm aware of Genton's work
on robust variograms but still look for papers.
Of course I would welcome a discussion about such topic.
Unless I'm completely out of date, most
Question about normal score transformation with regard to kriging.
I would like interpolate soil-parameters, which have been transformed by the
normal score transformation before. What should I consider with regard to
the backtransformation? Is a straight back-transform possible or is there
any
I'm working with GSLIB90, and I need to perform Universal krigin with a
lineal drift in vertical direction.
The question is:
a) It's necessary to calculate de variogram of residuals?
b) How to get the residuals (gslib90 can calculate can calculate de
drift, but first it need de
Dear Nicole,
We discussed this problem in the following paper:
Saito, H. and P. Goovaerts. 2000.
Geostatistical interpolation of positively skewed and
censored data in a dioxin contaminated site.
Environmental Science Technology, vol.34, No.19:
4228-4235.
We found that a straight
Hello All,
I'm looking some C codes to compute and fit (with spherical and exponential
models) experimental variograms.
I know that many software can do that, but I have more than 100 samples data
over which I have to generate the variograms and modeled them to find out
the range and sill values.
