Dear all,
I have a self-selection bias which I'm not sure whether could be corrected. I observe 6000 obs. of geo-referenced walking tracks (of 2500 families which were tracked using GPS for 24 hours). I do not observe motorized tracks, some of which have been carried to "walkable" destinations. The DV is distance walked (to be run over the terrain slope, land use characteristics, and participants' attributes).
Is there any way to correct or account for this bias?
I'll appreciate any hint!
Anat
