Dr Frederik P Agterberg in his eulogy called him “founder of spatial statistics”.

Yet, between 19 Professor Dr Georges Matheron did not teach his disciples how to test for spatial dependence and how to count degrees of freedom.

Pearson worked with large data sets whereas Fisher worked with small data sets.

That was what inspired Fisher to add degrees of freedom to Pearson’s chi-square distribution. Degrees of freedom converted probability theory into applied statistics, and sampling theory into sampling practice.

Sampling variogram shows whether, where and when it does.

We had studied David’s 1977 Geostatistical Ore Reserve Estimation.Professor Dr Michel David did not show how to test for spatial dependence and how to count degrees of freedom.Our paper was submitted to CIM Bulletin on September 28, 1989.My son and I wrote Precision Estimates for Ore Reserves.It was based on applied statistics as it had been developed by Fisher and Pearson and was praised by Wells.

Fisher and Pearson were both outstanding statisticians.
