Dear Dr van den Boogaart, Im pleased Cauchy is in no way associated with geostatistics but find your coin tossing function rather ironic in this context. May I respectfully remind you that geologists work with test results for core samples from one or more ore zones in a single borehole, and for multiple ore zones, either on a line or on a grid of boreholes. Contrived and useless examples have little appeal to those who want know how to derive unbiased confidence limits for metal contents and grades of ore reserves. You toss and toil with a silly application where degrees of freedom are irrelevant. Even though Im still gaining valuable insights in the world of geostatistics, I must suspend my participation in this fruitless debate indefinitely. Geostatistically engineered ore reserves may have served the mining industry quite well but mathematical statistics will serve and protect mining investors. I'll do what I can to make it happen! Kind regards, Jan W Merks |
