I have a raster surface that shows the relative difficulty of moving across terrain within the raster area. I also have a point feature class. I want to determine if there is a relationship between the values of the raster and the presence/absence of points in the feature class. How should I go about doing this?
I have used the 'extract values to points' tool to identify the raster value at each point location. I am thinking I want to do a logistic generalized linear regression, with the variables being the raster value and the presence/absence data but am not sure how to include the absence data. Any advice?
You would have to mask the point locations on the raster that represent your presence data, then convert the remaining raster to points
