latex_name = ('N', 'R', 'B', 'p_\\textrm{deactivation}')

Attributes

Npandas.DataFrame, dtype float

Fundamental matrix of the Markov-chain macro atom. Indexed by source_level_idx, destination_level_idx. Expected number of visits to destination_level_idx starting from souce_level_idx (before being absorbed).

Rpandas.DataFrame, dtype float

Deactivation probabilities of the Markov-chain macro atom. Indexed by source_level_idx. Probability of deactivation/absorption in source_level_idx.

Bpandas.DataFrame, dtype float

Absorbing probabilities of the Markov-chain macro atom. Indexed by source_level_idx, destination_level_idx. Probability of being absorbed in destination_level_idx when starting from source_level_idx.

p_deactivationpandas.DataFrame, dtype float

Redistribution probabilities after deactivation of the Markov-chain macro atom. Indexed by source_level_idx, destination_level_idx. Probability of an r-packet being emitted in the transition (source_level_idx –> destination_level_idx) after deactivation in source_level_idx.

outputs = ('N', 'R', 'B', 'p_deactivation')
