This tab displays Homophily, Affiliation, and Average Network Sizes.

Adjusted Average Network Sizes
Network sizes are adjusted for sampling bias. In a chain referral sample, those with
more connections and larger personal network sizes tend to be over-represented in the
sample. This can potentially bias sample estimates. (To learn more about the methods
used refer to: "Sampling and Estimation in Hidden Populations Using RespondentDriven Sampling" by Douglas Heckathorn and Mathew Salganik).
Unadjusted Network Sizes
Straight-forward arithmetic mean of the sample’s network sizes.
Homophily
A measure of preference for connections to one's own group. Varies between -1
(completely heterophilous) and +1 (completely homophilous).
Affiliation Matrix
Displays the same preference measures as homophily, but for all group pairs.
