[ai-geostats] gslib and simulations with 5 categories

2005-05-04 Thread gianni
Hi I have 1 categorical variable (transmissivity), with 5 possible outcomes s=1,2,3,4,5 from very low to very high. I have already created simulations with sisim, but i need now to create simulations with 2 outcomes:high and low, but at the same time using the informations i have and then i

[ai-geostats] A quasi-stationary framework...

2005-05-04 Thread Simone Sammartino
It's me again!...:-)) My problem now is: about a quasi-stationary framework... Assume Z(x) is not exactly stationary but its mean varies weakly in the space... Thus E[Z(x)]=m(x)...let's consider a new variable, said residual, Y(x)=Z(x)-m(x), with zero mean. Variogram for Z(x) is (1)
