Hello dears
I have a spatial data set contaning n=262 observarion (The variable of interest is
Rate of Tuberculosis in 262 counties of Iran). I want to fit some models to
Directional semi-variograms,and then build anisotropic semi-variogram.
Then questions are
- Is there any rule for choosing Lag Distance and Angular Tolerance?
-Also,how we can balance between Lag Distance and Angular Tolerance?
-Do you agree that both must be very small,as possible?(Such that number of pairs in
each lag>20, for example)
Thank you
