Hello,
I have a (simple) query about correlated random walks, or rather two of
the calculations involved.
Given that angle 1 is the angle turned at the end of move 1, and angle n-1
is the angle turned at the end of move n-1, where does move n fit into the
equation?
Am I to assume that in the calculation of the mean move length and the
average cosine of the turning angle, I leave out move n when I want to
calculate E(R^2n), so only take the means of cosines 1 to n-1 and lengths 1
to n-1?
Or is there some other way in which the mean cosines and move lengths are
calculated?
(the main source of confusion is that when an organism comes to rest, it
does not turn, so there is no turning angle associated with that move, so
do I leave out the final move, or include a turning angle of 0. Or
something else?)
thanks to anyone who can help.
