Dear Afani: The firs answer: See the attached figure.The second answer: In the Krige's relation all the variances are dispersion (or fluctuation) variances. These variances not depends on the data values (as the kriging variance). Then there is not relation with the kriging variance and the krige relation.

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 Krige’s additive relation can be written as: σ 2 (s,V) = σ2(s,v) + σ2(v,V)But how is: σ2(s,V) related to σ2ok? (σ2okKriging variance), under what condition?Abani R Samal Lakewood, CO __________________________________________________ Do You Yahoo!?Tired of spam? Yahoo!
