[Rsiena-help] outdegree W activity effect with bipartite dyadic covariate

[Guido Conaldi]

Dear Ruth,

I am trying to model the evolution of a bipartite network (X) including
a 2-mode dyadic covariate (W). 

I have been able to include the basic effect of W on X and now I would
like to include outdegree W activity effect, however I am not able to
find neither its shortName in the effect list nor the effect in my
sienaEffects object.
Any suggestion?

Thank you in advance,
Regards,
Guido
