Sorry I meant I am trying to gain, a better understanding of the derivation of the estimation variance used for the kriging equations. I understand the derivation is based on a number of assumptions, which I am trying to understand the effect of these assumptions. e.g. using mean values, unbiassedness etc. I am reading Chapter 10 of Isobels book, which seems to be the greatest help.

Is it a shortcoming of the mean to represent only average values? And is this a major shortcoming of statistics or of math? No, it is the aim of the mean to represent that and the mean is a tool of statistics for this purpose. Prof. Dr. K. Gerald v.d.
