836AI-GEOSTATS: Experimental variograms.
- Jan 12, 2003Hello,
When one calculates an experimental variogram used for spatial
modelling one averages the semivariogram values at each distance.
This value is just an average with a certain variance and coefficient
of variation which we assume to represent the true underlying
variogram as we only have samples of the entire population. To this
effect can anyone suggest any literature that which discusses
individual variogram variances and the effect of these assumptions,
and smoothing it may cause in our modelling, or is that our averaged
estimates of the variogram are accurate represenations as in many
cases they do produce smooth curves.
Thanks in advance.
