- msmbuilder.tpt.calculate_all_hub_scores(tprob)[source]¶
Calculate the hub scores for all states in a network defined by tprob.
The “hub score” is a measure of how well traveled a certain state or set of states is in a network. Specifically, it is the fraction of times that a walker visits a state en route from some state A to another state B, averaged over all combinations of A and B.
Parameters: tprob : matrix
The transition probability matrix
Returns: Hc_array : nd_array, float
The hub score for each state in tprob
