...radii (100m, 250m, 500m, 1000m and 2000m). For each radii I have generated a set of all possible models from the given 7 variables related to this radii. I have tried to account for random effects. A spatial random effect ? the structure itself as a repeated measurement, by adding the term (1|Road_Structure). A temporal random effect ? the observation session (is it correct to say that this examines possible learning in time ?), by adding the term (1|Session.ord). I have generated 4 sets for each radii: 1) with both random effects, 2+3) only one (each) random effect, and 4) none. I have tried...
