Re: [R-sig-Geo] Iteratively Reweighted Generalized Least Squares IRWGLS

Hi All, I think sgeostat function fit.variogram does it. Thanks. Faye ___ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo

[R-sig-Geo] Iteratively Reweighted Generalized Least Squares IRWGLS

Hi All, Do you know if R has a function to perform Iteratively Reweighted Generalized Least Squares IRWGLS? Thanks. Faye [[alternative HTML version deleted]] ___ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/lis

[R-sig-Geo] multivariable variogram modeling

Hi All, I forgot to add that zerodist worked out well. Thanks. Faye ___ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo

[R-sig-Geo] multivariable variogram modeling

You might consider posting to r-sig-geo next time, so others may enjoy the discussion and may even answer. The most common situation for this is that you have duplicate observations (use function zerodist to find out), or you have perfectly correlated variables; use correct.diagonal argument in fi

[R-sig-Geo] anisotropy

Hi, I wonder if there's a quantitative test to help make a distinction between two variograms. Thanks. Faye [[alternative HTML version deleted]] ___ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig
