I am trying to run GWR using a single independent/explanatory variable (atmospheric PM10) to model the relationship with a dependent variable, and it gives me the 040038 error. According to ArcMap help this means:
"040038 : Results cannot be computed because of severe model design problems. Results cannot be computed when there is either severe global or severe local multicollinearity (redundancy among model explanatory variables)".
This confuses me since there is only one explanatory variable so there can't be "redundancy among model explanatory variables". I wonder if this may be happening due to high spatial autocorrelation within the explanatory variable. What might be the issue, and how could it be fixed?
