Sum of ages of extant ties
# binary: edge.ages
This term adds one statistic equaling sum, over all ties present in the network, of the amount of time elapsed since formation.
Unlike mean.age , this statistic is well-defined on an empty network. However, if used as a target, it appears to produce highly biased dissolution parameter estimates if the goal is to get an intended average duration.
