Coefficients of variation, ms.

CV () calculated for a 3 s simulation and 5000 trials for each of Case 1: Fixed number of steps to shutoff and random sojourn times ; Case 2: Fixed sojourn times and random number of steps to ; Case 3: Both sojourn times and shutoff steps are random. The parameters and and their equivalence for WT mouse are discussed in the section Parameters. The theoretical values of are reported for 3-6P as the theoretical formula of Eq:3-Eq:4 is valid only for these cases.
