InitErgmTerm.absdiffby(nw, arglist, ...)

Arguments

  • nw: An object of class network.

  • arglist: A list of arguments as specified in the ergm.userterms

    package framework.

Details

This ERGM user term was written to allow for age-based homophily in partnership formation that is asymmetric by sex. The absdiff component targets age-based homophily while the by component allows that to be structured by a binary attribute such as "male", in order to enforce an offset in the average difference. This allows, for example, a average age difference in partnerships, but with males (on average) older than females.
