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

[Christian Steglich]

Hi Guido,

as addendum: if you want to have the effect for a dyadic covariate W, 
you can calculate the outdegree in the W network (or the square root of 
it) as an actor covariate outside RSiena, and use it as normal actor 
covariate in SienaDataCreate. The ego effect fior this covariate then 
expresses exactly what you need (the extent to which actors with high 
outdegrees on W will make more choices in the X network).
