Some issues in Simple_Kriging_Demo.xlsx #2
Description
Hello and hope you are doing well.
First I have to appreciate your efforts on providing useful resources.
I was checking Simple_Kriging_Demo.xlsx file and I think I came across some errors in it.
1 - In the matrix number 4, its diagonal elements are set to fixed value 0. It has to be equal to the nugget!
2 - In the matrix number 5, I think covariance are being calculated in a wrong way because if I'm not wrong, we know that:
Covariance + Variogram = Sill (spherical) but when I inspect the cell formula I find something different
I'm glad if you could help me with mentioned issues ( maybe I'm wrong )
Thanks in advance.
