Re: AI-GEOSTATS: variogram model of n-scores in SGS

2002-07-08 Thread Pierre Goovaerts
Hi Carlo, Note that a sill strongly different from 1 would mean that the assumption of 2nd order stationarity underlying SGS is not met. I wouldn't force the sill to be one when fitting the model and you have to use a unit sill model in the simulation program for consistency. If the deviation

AI-GEOSTATS: Optimal Kriging parameters

2002-07-08 Thread Eva Pierce
Hi. I want to use Ordinary Kriging on an arbitrary dataset of X,Y, and Z values to estimate the Z values on a grid of arbitrary size/density. But I dont know what length and scale parameters to choose for the semivariogram. So I need to answer the following questions. Im looking for
