Emmanuel, I'm completely new to the idea of cross validating conditional simulation. Wouldn't the outcome be different each time you do it? Do you have some reference to people who did this before you?
I can think of reasons why the error you get occurs. But should it be fixed? -- Edzer

Hi all, I tried to do a cross validation of a gaussian simulation. I put xvalid = 1 in the command file, but always get this :
[using conditional gaussian simulation]
"chfactor.c", line 130: singular matrix in function LDLfactor()
gstat caught an error that occurred in the matrix library, the reason for it was: singular matrix
HINT: Read the manual at http://www.gstat.org/ ; look for: Trouble shooting -> Error messages -> From meschach
gstat: matrix library error: singular matrix
I did have a look to the documentation and tried the solutions explained there but with no success.
Does anybody have an idear ?
