Efficient updating of kriging estimates and variances
What is more, his drill-core samples varied in length.
As a result, the number of degrees of freedom is a positive irrational rather than a positive integer.
All it took was a young French geologist who went to work at a mine in Algeria in 1954.
He measured associative dependence between lead and silver grades of drill-core samples. So, he did not know whether his correlation coefficient was significant at 95%, 99% or 99.9% probability.
I was asked to cite a specific reference for the quotation in which H G Wells spoke so highly about statistical thinking.
His students thought of him as “creator of geostatistics”.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.Geostatistics messed up the study of climate change.Spatial dependence in our sample space of time may or may not dissipate into randomness.We did not criticize geostatistics nor did we refer to it.CIM Bulletin rejected it but Erzmetall praised and published it in October 1991.Applied statistics shall stand the test of time until our sun bloats into a red giant and Van Gogh’s Sun Flowers burn to a crisp.Why did geoscientists get into geostatistical thinking?Fisher and Pearson were both outstanding statisticians.They inspired H G Wells and scores of statisticians.
