Run

When pressing the run button, the calculations are done, the Global Metal and Tonnage Table are reported in the message window and the Geostatistical Set is updated.

The support correction statistics are as follow:

  • Point Variance (Anamorphosis): Input raw data variance (on the point support), as stored in the anamorphosis function of the geoset.
  • Variogram Sill: Sill of the raw point variogram.
  • Gamma(v,v) (Only for DGM1): The overall loss of variance when going from point to block.
  • Real Block Variance (Only for DGM1): The resultant overall block variance.
  • Real Block Support Correction (r): This is the change of support coefficient from points to blocks, i.e. the correlation between the Gaussian block value and the Gaussian value of a point randomly located within the block.
  • Information effect parameters (Only for DGM1): The Kriged SMU Variance(Variance of Z*) and the Kriged-Real Block Covariance (Covariance between Z and Z*) are calculated from the defined final sampling mesh and the raw variogram. They can also be found in the input parameters in the task.
  • Kriged Block Support Correction (s) (Only for DGM1): This is the change of support coefficient taking the information effect into account, i.e. the correlation between the Gaussian Kriged block value and the Gaussian value of a point randomly located within the block. It is calculated only when the information effect has previously been calculated.
  • Point/Block Selectivity Coefficient: The selectivity coefficient, also known as the Gini coefficient, or the selectivity index, is equal to the dispersion indicator divided by the mean grade. It is minimal (close to 0) if the ore has a uniform grade distribution equal to the mean grade (no selectivity). It is maximal (close to 1) if the ore is condensed in few samples with very high grades (high block selectivity).
  • Kriged-Real Block Support Correction (Only for DGM1): Support correction coefficient taking account the information effect.
  • Block anamorphosis range:
    • Zmin Block: Minimum possible block value.
    • Zmax Block: Maximum possible block value.
