[ai-geostats] regularization

2004-10-26 Thread samuel verstraete
est sample. Question is... Is there any other literature that discusses this matter and even more importantly is there any software out there that can take this sampling support into consideration when I'm calculating the variogram or when I start with estimation/simulation of the field.

[ai-geostats] normality of data

2005-05-02 Thread samuel verstraete
Hello list, I know that normality is not required to do geostatistical analysis of (georeferenced) data. Still I'm unable to find any publication that refers to this statement to which i can refer. Any suggestions? Greetz, Samuel Verstraete * By using the ai-geostats mailing lis

[ai-geostats] validation with gslib

2005-05-13 Thread samuel verstraete
Hi, Working with GSlib i wondered if anybody ever adjusted the simulation procedures (sgsim, iksim, dtsim...) so you can actually perform an independent validation? So not crossvalidation off course, but in my opinion a jackkniving should be possible. If you could first simulate the complete grid

[ai-geostats] dssim-HR

2006-02-17 Thread samuel verstraete
