The imitation process appears to be independent of imi_p_imitate both for 'simple' and 'complex' contagion. Setting it to 0.1 or 1.0 makes no difference. For the 'simple' case even setting it to 0.0 does not stop imitation.

example config:

culture = M.Culture(
    imi_rate = {
        'bool': 100,   # -> 10000 updates
        'ord': 0,  # *10 in batch -> 10000 updates
        'pair': 0, # *~50 in batch -> 10000 updates
        '*': 0,
        },
    imi_type = 'complex',
    imi_batch_n = {'bool': 2, 'ord': 10},
    imi_p_in_batch = {'pair': 0.5},
    imi_network = M.Culture.acquaintance_network,
    imi_p_neighbor_drawn = {'pair': 1.0},
    imi_n_neighbors_drawn = {'bool': 10, 'ord': 20},
    imi_rel_threshold = {'bool': { 
            ((False,),(True,)): 0.0, 
            ((True,),(False,)): 0.0
        }},
    imi_abs_threshold = {'ord': 2, 'pair': 0},
    imi_include_own_trait = {'pair': True, '*': False},
    imi_delta = {'pair': 10.0},  # evaluation will be done by Individual.imi_evaluate_pair
    imi_p_imitate = {'pair': 1.0, 'bool': 0.0}  # for 'ord', the value is set by Cell.imi_p_imitate_ord
    )

Another error with imi_p_imitate: Setting it only for some of the traits (e.g. all but 'bool') yields an error message. Not setting it at all does not. It then shows the same behavior as setting it to any specific value (as in the bug described above).

When not setting a value for a specific trait, imi_p_imitate should be set to default. Also: I could not find any defaults in the documentation for the parameters.

To replicate use above config but change:

    imi_p_imitate = {'pair': 1.0}  # for 'ord', the value is set by Cell.imi_p_imitate_ord

the default can be set this way:

    imi_p_imitate = {'pair': 1.0, '*': 0.0}
