I am trying to perform regression analysis using road accident data using ArcMap 10.1. The accident data is a point file for all accidents with information on the date the accident happened, time, male or female, weather conditions, vehicle manoeuvre etc, very detailed.
I also have a polygon data set of census tracts. My issue is that I can join the two but only get a column containing the total number of incidents (accidents) per census tract.
How can I perform regression analysis using data at 2 different scales?
The independent variables I am interested in are contained in the point data set.
