Occupancy Variance 1.
Imagine repeating Markov sequence many times (L??), each time taking a fixed number of steps, M
- tabulate histogram for each sequence;
- examine variances in occupancy fraction
-
-
- through propagation of error, the occupancy (co)variances sum to give the variances in the ensemble averages; e.g. (for a 2-state system)
-
-
- we would like these to be small
