Note. LGBT = lesbian, gay, bisexual, transgender; API = Asian American/Pacific Islander; SES = socioeconomic status; GWESP = geometrically weighted edgewise shared partner; GWDegree = geometrically weighted degree statistic; GWDSP = geometrically weighted dyadwise shared partnerships; AIC = Akaike information criterion.
The tendency for 2 network partners who were directly linked to have multiple shared partners.
The number of direct connections each network member had with other members.
The tendency for any 2 network partners (linked or not) to have shared partnerships.
Model comparison delta-p. The structural model is compared to a null-baseline model; the structural plus organizational model is compared to the structural model.
