Hello
                

I'm analyzing road mortality data which was collected as binary data (ie presence/pseudoabsence). I am new to spatial data, and thus have been struggling when trying to assess spatial autocorrelation. I've tried to use spline correlograms because they are robust with binary data, but am not sure if I'm violating any assumptions since I'm dealing with quasi one-dimensional data. Also, the data was not sampled at evenly spaced intervals, but rather the mortalities ("presence") were measured where they occured, and the "pseudo-absence" locations were randomly generated. 


Does anybody have suggestions as to how to proceed? Any help highly appreciated!

Thank you very much,

Mirjam
