GWR and Jarque-Bera Statistic

Discussion created by lkh344 on Jun 1, 2013
Hello All,

I ran OLS model before checking the variations of the relationship using GWR. The OLS model shows that Jarque-Bera value is not significant but BP value is significant. So I interpreted the OLS model need to check non-stationality by using GWR. However, there is no model biased problem.

The other model shows different statistical diagnostics (please see the below). My questions is are the following: if both BP and Jarque-Bera test are significant, GWR model could reduce model bias problem? If so, how can I check this in Arcgis?

Thank you and hope hear soon.
