      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.
