# binary: edgecov.ages(x, attrname=NULL)

a specification for the dyadic covariate: either one of the following, or the name of a network attribute containing one of the following:

This term adds one statistic equaling sum, over all ties present in the network, of the amount of time elapsed since formation, multiplied by a dyadic covariate.
"Weights" can be negative.

, 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.
