Great, thanks Eric!

Wonderful, thanks Eric! I am trying to find the model that's the least bad for the other two relationships when selected for a given relationship. It seems especially hard to find any model to fit the covariance graph, so I am prioritizing fitting Var1 - Var2, then Var2 - Var2, then Var1 - 2.

Thanks so much Eric! You helped clear up a lot of my confusion. It sounds like it is not possible to select different models for different relationships, that there is a single suite of one or more models that is supposed to apply to all three relationships, both with or without the optimize button? Which diagnostics would you recommend beyond RMS for selecting the best model? Good point about the example I pointed to being above zero. In my own data unfortunately I have a truly negative correlation--see attached. What would you recommend I do for this situation if Geostatistical Analyst only accommodates positive relationships?

Thanks for the link on general concepts of semivariogram and covariance functions, Steve. My questions above are focused on the specific mechanics of how Geostatistical Wizard implements these concepts to know step-by-step how to optimize all three relationships (Var1 - Var1, Var1 - Var2, Var2 - Var2) correctly.

Thanks for explaining, Eric, but I'm afraid that I am still confused. Are your results from hitting the Optimize button independent of the model selected such that it's not necessary for the user to determine the best model? That's the only way I can think of that it could optimize three different relationships (Var 1 - Var1, Var1 - Var2, Var2 - Var2) that likely have three different best models. If optimize is dependent on the model selected, after I hit it and then want to try an alternative model, do I need to close the wizard to avoid multiple optimizations compounding changes from the true data? You say that if you don't want to rely on the optimize model button, you can manually specify the paramenters for all three covariance models, so that means I can select different models for each relationship by displaying them one at a time and selecting a model for each one as long that will be applied only to that relationship, or does the wizard only accommodate a single suite of Model #1 + Model #2, etc. for all relationships? Figure 11 of the paper Multivariate oil and gas data interpolation: data exploration and modeling shows a negative covariance model in Geostatistical Wizard, so I know it is possible somehow. Thanks for helping me figure this out!

I am disappointed by the lack of documentation walking users step-by-step through Geostatistical Wizard. Is the correct sequence to follow? 1. Select model(s) for best fit of semivariogram of Var1 - Var1 and then optimize that model(s) 2. Select model(s) for best fit of covariance graph of Var1 - Var2 and then optimize this model, or does this somehow overwrite the model you selected and optimized for Var1 - Var1? 3. Select model(s) for best fit of semivariogram of Var2 - Var2 and then optimize that model(s), or does this somehow overwrite the models you selected and optimized for the other variable combinations above? 4. Proceed to searching neighborhood and cross validation steps Can you reoptimize for a different model if the semivariogram looks horrible after your first optimization, or did the first optimization already distort the data such that you should close out of Geostatistical Wizard and start again from scratch? How can you fit a model to a negative correlation between the two variables? All the model options create curves of positive correlations only, unless there is a setting for this that I am missing? Eric Krause or anyone else knowledgeable about Geostatistical Wizard, could you help me? Thanks in advance for any help that you can provide.

Thanks for letting me know, Mike!

Hi, I would like to use a "replace all" function to replace our test environment urls of ArcGIS Server-hosted map services referenced in the map http://tnc.maps.arcgis.com/home/webmap/viewer.html?webmap=e276bf141dfb4459b0f900b85d252dfd&extent=-89.021,44.3552,-85.0824,46.006 with production environment urls to avoid having to add the production services and reconfigure all the pop-ups. Can anyone tell me where to access the source code that an ArcGIS Online map uses to grab the indicated services so I can use a text editor to redirect it to the production map services? Thanks!

Robert Scheitlein answered my questions when I started a new thread. See http://forums.arcgis.com/threads/78109-missing-labels-and-pop-ups-in-feature-services?p=274679&posted=1#post274679 . Thanks to both of you for your help!

Allison, The only one that can be fixed is the popups (as far as you using FV 2.4). <layer label="Top 50 Fish Barrier Removal Priorities" type="feature" visible="true" alpha="1" popupconfig="popups/RSX.xml" useamf="false" url="http://services.arcgis.com/F7DSX1DSNSiWmOqh/ArcGIS/rest/services/WIFO_GBT_DUCK_RSX_TOP/FeatureServer/0"/> The labels are not going to show up as labels/annotation is not supported with type="feature". The no symbology appears in the TOC widget when using layers from ArcGIS Online accounts was not fixed until version 3.x Duh, there are no sublayers in feature services to need to specify sublayer ID! Thanks for the info on the limitations of feature services. You always hit the hammer on the head, Robert!
