Hello AI-Geostats members
I saw Marrons I Statistic in GS+ Software. It is an statistic computed in each lags as
follow:
N(h){sum(Zi*Zj)/sum(Zi^2)}
This statistics and its plot arise for me two problem:
- Is it the correlation function?
- How can interpret this statistics or its plot?
(Also I think that N(h) needs the power -1, i.e 1/N(h) is the correct not N(h)!).
I have another question about GS+ method for semi-variogram model fitting:
--- By which method GS+ estimates the parameters of semi-variogram? (By Least Square,
Generalized Least Square, Maximum Likelihood,...?)
