transmission_tree
()[source]¶ Produces a MultiDigraph whose edges correspond to transmission events. If SIR, then this is a tree (or a forest).
Returns: - T a directed Multi graph
- T has all the information in
transmissions
. An edge from u to v with time t means u transmitted to v at time t.
Warning: Although we refer to this as a “tree”, if the disease is SIS, there are likely to be cycles and/or repeated edges. If the disease is SIR but there are multiple initial infections, then this will be a “forest”.
If it’s an SIR, then this is a tree (or forest).
The graph contains only those nodes that are infected at some point.
