Both are logistic network regression models (will include some referecnes) and are of the form: Y=b0 + b1*X1 + b2*X2 + e where for the blog-blog: BlogByBlog = b0+b1*Bandwagon + b2*BlogPartyLeaning + e and where for the vid-by-vid colinking version: VidByVid = b0+b1*BlogLink2VidCount + b2*VidPartyLeaning + e BlogLink2VidCount: this is setup the same was as I did for the bandwagon but uses the counts of times a blog linked to a video instead of video views.
