Spatial Analysis Tools and State-Level Data

monstera

Hi,

I'm using ArcMap 10.8.2 to analyze data from a table that has U.S. state-level data (50 data points).  I have tried a few different tools (high/low clustering, exploratory regression, geographically weighted regression, spatial autocorrelation (Morans I) , and I get errors no matter what I try.  Errors messages mention invalid parameters, unexpected error (999998), or Error 040038.  Might this be because I don't have enough data points (due to having just one value per state rather than county-level values, i.e., many values per state), or is something else wrong?  All of the variables I want to explore are numeric with no other characters except a decimal point, and these variables are all available for selection in the tools I'm using.  My input variable of interest shows up when I select the correct layer, and everything else, to my knowledge, looks okay.  I can't share the data but I have 50 lines of data and my columns of interest are rates or percentages expressed with a decimal point (no %).  

Thanks!

Is your data associated with any geometry? If not, you can download the state polygons from the Living Atlas and join the table data to it. Once your data is associated with polygons, those tools should work well. 

If your data IS associated with polygons and you're getting those errors, try using repair geometry ? Otherwise, copy the layer, remove all the fields, add a numeric field (add field, then calculate the field to match the object ID field, for example), then see if you still get errors running those tools on the new field. If you do, the issue is your geometry. Consider downloading the state polygons from Living Atlas instead of using your current geometry (if you need points instead of polygons, you can use the feature to point tool). If removing the fields corrects the problem, the issue is with one of your fields. See if you can pinpoint which field(s) are creating the problem.

I hope this helps!
