I'm a bit confused about the unit in movement_var from estimate_movement_var, as well as the resulting transition matrix using the RandomWalk transition type.
From the code it seems the unit of the returned movement_var is length / second. In make_state_transition, however, the transition probability is computed using the variance given by estinate_movement_var directly, without dividing it by the sampling frequency in the decoding problem. This means if my time bin for the decoded data is 0.1s, I'm still using a degree of smoothing as if my time bin were 1s.
Is this a correct interpretation of what the code is doing? Thanks!
