Hi all, I'm new to the list, so bear with me :) I'm trying to carry out some kriging of some (x,y,v) data set on to a regular grid. I have read some of the...
Dear List: I am trying to build a porosity control map using a discrete log with 7 facies, using sequential indicator simulation. The lag size must be set ...
Corinne The whole point (as I understand it) of using an indicator approach is to remove all question of what the original distribution was. All your sample...
Dear Geostat I'm a beginner and I had the unliky case of a tridimensional multivariate geochemical dataset to start my geostatistical adventure...moreover data...
Group: To add to my previous question, I have a continuous dataset of spectral readings from local crops. Under the idea of spatial continuity I would assume...
Hello Group: Being new to geostatistics I am unsure about the various types and modes of spatial analysis. Is there a way to determine the probability of...
Dear Group members Would you suggest any document on the use of the method MAXIMUM LIKELIHOOD to fit a model to experimental covariogram, preferably at a level...
Dear list members, I'm trying to build a spatial simulation model of population dynamics and wanted to ask for your input and suggestions on how to accomplish...
Thanks to Isobel Clark: I have a sub-set of data that does not appear to be anisotropic, nor does it contain "bad" outliers; however, my kriging of this data...
Hi- It has been my habit to fit a variogram models as NUG + SPH + SPH omnidirectionally to get Nugget and two partial sills and then use these values it other...
Hi Samuel, I have dealt with similar problems when analyzing the spatial distribution of dioxin and other heavy metals in river sediments. Core lengths can...
Group: I have a sub-set of data that does not appear to be anisotropic, nor does it contain "bad" outliers; however, my kriging of this data errors out the...
Hi Andrew, A critical piece of information is the objective function you want to optimize. I have worked in the field of optimization of sampling design...
Dear forum members, We are using nested model with geometrical anizotropy to remove artificial imprints connected to high frequency measurement errors along...
Greetings, I am coding some basic geostatistical estimators, including the variogram, and would like to find some sample data sets for testing. Can someone...
Dear ai-geostats Members, Are there appropriate statistical tests for determining whether empirical variograms are statistically different (maybe something...
Mark We have about 13 data sets available on our free download site, ranging from mining data to fisheries, agriculture and environmental stuff. Number of data...
Hello mail list I have a set of profile of GPR data in format *.rad and *.rd3 where I can download a freeware for convert in e grid? * By using the ai-geostats...
Hi, I have been trying to compare the autocorrelation of a dataset, using both spatial distance and other non spatial metrics. Yes, non spatial metrics (I'm a...
Dear List: I got a question about the uncertainty associated with the Conditional Stochastic Simulated results, the question is: I have soil C data for a...
Hi, I am wondering if you have any thought on this interpretation: Supposing i have 2 different data sets X and Y. I know that both data sets are actually a...
xhy your questions are long-standing and as yet unanswered in general. ... I always think of it as focussing a camera. Believe there is a pattern in your data...
VAR[X]=E[X^2]-E[X]^2=E[X(X-1)]+E[X]-E[X]^2 I have received a document where they make emphasis in the expression E[X(X-1)] it have some special meaning or...
Mark - you'll find a list of free GIS packages on this website: http://freegis.org/ One of the most comprehensive free and open source GIS is GRASS, which is...
Dear everyone, I'm new to this mailing list and the field of geostatistics, so my question might be too obvious, but I don't have anyone around to get some...
Hello list, First of all, thanks for the many replies to my last question. That was really helpful. Thanks !! Now I have an additional question (and hope it is...
Hello All, I'm not sure if this is the correct forum for this.but a colleague has asked a question I'd like to address. This fellow wants to predict the...
Please find hereafter the last call for a scientific exercise dedicated to spatial statistics called SIC2004. SIC2004 stands for Spatial Interpolation...
