[edit] All Wikipedians and all Krige's men cannot put the distance-weighted average and its variance together again!

How utterly ridiculous for those who want to bring knowledge to the world.--Iconoclast 19:48, 16 April 2006 (UTC)

Wikipedians may well do what Krige's men failed to do! JWM.--Iconoclast 21:13, 29 July 2006 (UTC)

Why dont you add an article on stochastic simulation in geography? The letter you refer to seems to indicate that this is the correct approach, at least for reproduction of spatial variability. My question would then be whether kriging is in fact an estimation of spatial variability. SCmurky 02:49, 29 July 2006 (UTC)

What should be done first of all is verify spatial dependence between measured values in the ordered set for the stochastic variable of interest. If the set does not display a significant degree of spatial dependence, then it is impossible to obtain unbiased distance-weighted averages and variances. If it does, however, any set of coordinates within the validated sample space gives an unbiased distance-weighted average, a variance and 95% confidence limits. In this case, stochastic simulation would give more but statistically identical stats. I've applied stochastic simulation for complex stochastic systems such as recoveries in metallurgical balances in mineral processing plants. I need to know what you propose to do before we take the next step. JWM. --Iconoclast 21:13, 29 July 2006 (UTC)
