Professor Dr Margaret Armstrong and Professor Dr Roussos Dimitrakopoulos rank amongst the most gifted geostatistocrats on our little planet. What a shame that they smooth data sets beyond the perfect fit! Dr RD is into stringing Markov chains between measured values! What he should not do is assume spatial dependence between measured values in ordered sets. What he ought to do is count degrees of freedom. Stringing Markov chains does not create spatial dependence anywhere in this universe!
