Hi Abani
You need my 1983 Mathematical Geology paper, "Regression Revisited" which can
be downloaded by folloing the publications link at
http://uk.geocities.com/drisobelclark/resume
Or, with less math, "A simple alternative to Disjunctive Kriging" written
with Flemming Clausen in 1981 (TransIMM). Also on the web.
I have seen later papers which propose similar with a lot more mathematics.
Hope this helps

My First question:
I am using a mining software to get a krigged block model. The tool also
saves a parameter called "Slope of Regression". The "Slope of Regression" is
defined as
(Block Variance Kriging Variance
+Lagrange_multiplier)/(Block_variance-KrigingVariance+2*abs(Lagrange_Multiplier))
provided the denominator is not zero.
Unfortunately, there is NO literature available (Including no help file). I
have hard time to understand what this "Slope of Regression"means and how this
slope is usable.
I'll highly appreciate your thought on this.
My second question:
If s is the sample, v is the block and V is the whole panel of blocks or the
whole deposit, the Kriges additive relation can be written as: ó 2 (s,V) =
ó2(s,v) + ó2(v,V)
But how is: ó2(s,V) related to ó2ok? (ó2okKriging variance), under what
condition?
