Bin,
May you explain better? I now that different graphs generate different
distributions of values that should not be compared directly, mainly
if the sizes are very different.
However RA and RRA are normalised by a "standard graph with a shape of
a diamond and the same size".
Does not it enable us to do a "sort of comparison", at least for
graphs with similar sizes?
Do you recommend something else (I am interested in this subject) ?
About pedestrian movement... databases may not help.
It point is endless...
We may say that correlate only in that case (of the database)
We may discuss the method used to count pedestrians and point that the
data and the experiments were not properly verified and reviewed.
We may say that, OK, the method is good and we found good
correlations, but it was coincidence!
:D
Regards,
Lucas
