AI-GEOSTATS: Choosing Lag Distance and Angular Tolerance

Lag Distance and Angular Tolerance? -Also,how we can balance between Lag Distance and Angular Tolerance? -Do you agree that both must be very small,as possible?(Such that number of pairs in each lag20, for example) Thank you Yadollah Waghei Dep.of Biostatistics Tarbiat Modarres Univ.(Tehran)Po.Box

AI-GEOSTATS: Need to SPLUS functions for Universal Kriging and Simulation...

Hello, Dear Members I work in Spatial Statistics context, and write my programs in SPLUS. Now I need to user written SPLUS functions for both Universal Kriging, and simulation random fields in 2-dimensional space. For simulation I have seen the article: E. Pardo_Iguzquiza and M.

AI-GEOSTATS: Estimating the fixed Sill in the Elliptic Anisotropy

Hi, AI-Geostats member In Elliptic Anisotropy we suppose that the Sill parameter of Variogram is fixed and the Range parametre is varying with direction, in an ellipce. But in practice, usually Sill is also depends to direction (more or less). My question is that: How can we estimate Sill and

AI-GEOSTATS: Anisotropy with varying Range and Sill

Hi AI-Geostats member I have an Anisotropic Spatial Data Set on which,Sill and Range (and also nugget effect) are both varying with direction, I need a method or refrence article for modelling the variogram structure of such data in 2-Dim. space. Please introduce a method and/or a reference
