Hi
Maybe you can ask to the authors of the various papers about
transition probabilities.
From what I remember in groundwater vista (or maybe GSM) t-prog is
implemented for modeling 3d geological architecture.

Dear list,
A would appreciate if someone give me tips about how to get T-PROGS software or
any other software about transition-probability-based geostatistics, preferably
free ones.
Thank you.

It would be very nice if there would be a tutorial on
how to use the variogram modeler.

Hi all,
for S or R users, GeoR is worth a look for auto-fitting procedures. This
R package allows fitting of variograms (with the option of trend
removal) via least squares (equal weights, n_pairs weights, or 'Cressie'
weights), or computationally using maximum liklihood or REML. If you go

Hi AllIt is difficult to have an automaticbest fit semi-variogram until you define what you mean by "best fit". Noel Cressie's goodness of fit statistic goes a long way towards the ideal, but is very insensitive to changes in nugget effect and pretty insensitive to fairly large changes in the

What weighting do you use in the weighted least squares?

I have found choosing suitable weights always a frustrating
event. Cressie's weights, let's say N_h/[(gamma(h))^2], has
attractive properties, both intuitively and statistically. Here,

EdI use the Cressie statistic to four significant figures as a guide in the interactive fitting, but generally end up using a visual judgement. It tracks as you drag the model around, so you can watch it change.I think the 'real' visual objective function is probably the perpendicular (to

I have one more request:
Maybe some one can recommend free software for median polish kriging (maybe i'm wrong but GSTAT software and R system not have a procedures for such kriging method)

Thanks to Pierre, Chris, Donald, Vassily and Tom for their suggestions in
my problem with GeoEas data files under W-XP. Saving the data file in
GeoEas format from Excel as formatted text space-delimited (*.prn)
(Pierre's suggestion) did allow to read and work the data in Variowin 2.21,
but alas!
Title: RES: AI-GEOSTATS: Update software glitches
Is there any specific reason for you to use GeoEas for cross-validation? I have no experience with your kind of problem, but I'd say try using GSLIB for cross-validation.
Good luck.

Dear colleagues,
I don't have much experience with geostatistics, but from now on I will use it in my
PhD-study on spatial variability in soil physical properties and hydrological
processes. I've been looking for the ultimate software for some time now,
Either use Gstat (www.gstat.org) or/and gslib (www.gslib.com).
Both maybe not as user friendly in the sense of nice GUIs as the software
you used so far. but they are very powerful and provide lots of methods
and oportunities to solve spatial stats problems. It is worth using them.
And they
