Hi! I am interested in creating a spatial regression model with ArcGis. I found the option to use GWR tool. All the information I fount about that is fine, however, I still have a question about a specific case that I have: My data is time dependent, there is a time lag between the cause (explanatory variable) and event (dependent variable). This time lag is different depending on lacation of event in ralatio to cause. How can I include time lag in my GWR? Should I use GTWR method for that purpose?
