topic GWR tool issue in Spatial Statistics Questions https://community.esri.com/t5/spatial-statistics-questions/gwr-tool-issue/m-p/650269#M2093 <HTML><HEAD></HEAD><BODY><SPAN>Hey I would be really appreciative if anyone can help me out with a problem I am having with the GWR tool.&nbsp; The GWR works fine when I run it on a particular shapefile.&nbsp; However I want to run a GWR where I need to add a field to the shapefile, and that is where the problem occurs.&nbsp; The original shapefile has fields for homicide rate in the United States in 1970 and 1980.&nbsp; I want to create a new field that has change in homicide rate between 1970 and 1980.&nbsp; To do this I just create a new field and use the field calculator to subtract the 1970 field from the 1980 field.&nbsp; Now when I try and run the GWR with this new field is my dependent variable I get an error.&nbsp; The error is something involving not having enough data to run the GWR.&nbsp; After I create the new field this error comes up every time, even when I don't use the newly created field as the dependent variable.&nbsp; Something happens when I create this new field so that the GWR no longer works for the entire dataset.&nbsp; Does anyone have any idea what is going on here?&nbsp; Any help would be very much appreciated.&nbsp; Thank you!!!</SPAN></BODY></HTML> Fri, 04 May 2012 23:12:19 GMT StephenFricke 2012-05-04T23:12:19Z GWR tool issue https://community.esri.com/t5/spatial-statistics-questions/gwr-tool-issue/m-p/650269#M2093 <HTML><HEAD></HEAD><BODY><SPAN>Hey I would be really appreciative if anyone can help me out with a problem I am having with the GWR tool.&nbsp; The GWR works fine when I run it on a particular shapefile.&nbsp; However I want to run a GWR where I need to add a field to the shapefile, and that is where the problem occurs.&nbsp; The original shapefile has fields for homicide rate in the United States in 1970 and 1980.&nbsp; I want to create a new field that has change in homicide rate between 1970 and 1980.&nbsp; To do this I just create a new field and use the field calculator to subtract the 1970 field from the 1980 field.&nbsp; Now when I try and run the GWR with this new field is my dependent variable I get an error.&nbsp; The error is something involving not having enough data to run the GWR.&nbsp; After I create the new field this error comes up every time, even when I don't use the newly created field as the dependent variable.&nbsp; Something happens when I create this new field so that the GWR no longer works for the entire dataset.&nbsp; Does anyone have any idea what is going on here?&nbsp; Any help would be very much appreciated.&nbsp; Thank you!!!</SPAN></BODY></HTML> Fri, 04 May 2012 23:12:19 GMT https://community.esri.com/t5/spatial-statistics-questions/gwr-tool-issue/m-p/650269#M2093 StephenFricke 2012-05-04T23:12:19Z
