It was William Volk who has written my favorite textbook! I have kept a copy of its 1958 edition on my desk when I was making a living in the Port of Rotterdam. What I like most of all in Applied Statistics for Engineers is that Volk explains the properties of variances in such rich detail. My first copy is falling apart but I’m still as smitten with its contents as I was in 1958. Volk pointed out in his Preface that he was indebted to Professor Sir Ronald A Fisher (1890-1962). It didn’t take long to figure out why Section 7.1.4 Variance of a General Function in Volk’s 1958 textbook proved that each function does have its own variance. Stripping the variance off the weighted average cum kriged estimate set the stage for Matheron’s new science of geostatistics. This fact became of critical importance when my grasp of the properties of variances made it possible to prove that the intrinsic variance of Bre-X’s gold was statistically identical to zero. So I’m pleased that the properties of variances did indeed stand the test of time in Volk’s Applied Statistics for Engineers.
What did not stand the test of time are degrees of freedom. The concept of degrees of freedom is relevant in applied statistics but irrelevant in geostatistics. Degrees of freedom would have vanished without a trace if it were not for Table1.IV. Copper grade Prince Lyell in David’s 1977 Geostatistical Ore Reserve Estimation. Grant NRC7035 made it possible to put so much junk stats on paper. I have always applied Fisher’s F-test to prove spatial dependence between measured values in ordered sets. I did so with test results for ordered core sections from single boreholes but also with test results for ordered sets of on-stream measurements in mineral processing plants. Should Matheronian geostatistics be an integral part of geosciences? Or should it be rejected as a scientific fraud? Of course, it should be rejected! If only because geostatistics is messing up the study of climate dynamics!
Sir Ronald A Fisher (1890-1962) was knighted since he counted degrees of freedom for small data sets. Karl Pearson (1857-1936) devised the chi-squared distribution in terms of observed and expected ratios. He did so in his Galton Laboratory. Sir Ronald A Fisher went to Australia and worked for a while at CSIRO (Commonwealth Scientific and Industrial Research Organization). He passed away in 1962 and was put to rest in Adelaide. He has never been awarded a Nobel price. My confidence in Sir Ronald A Fisher and his famous F-test is bound to last far beyond my time.
Margaret Armstrong migrated to France after she had completed her Master’s degree in mathematical statistics at the University of Queensland in the 1990s. Between Australia and CERNA, Mines Paris Tech, France, she may have paid too little attention Matheron’s new science of geostatistics. Or Matheron may not have told her that he had flunked his PhD thesis in 1965. But surely, Armstrong should have known all about Fisher’s F-test and about counting degrees of freedom. She could have told Professor Georges Matheron all about counting degrees of freedom. Why did Matheron confer on Armstrong a PhD in geostatistics s0 shortly after she had left Down Under and made landfall in the City of Lights?
