DESCRIPTION:Co-authors: Krista J. Gile (University of Ma
ssachusetts at Amherst)\, Mark S. Handcock (Unive
rsity of California\, Los Angeles)
It is common in the analysis of social net
work data to assume that it represents a census o
f the networked population of interest. Often the
data result from sampling of the networked popula
tion via a known mechanism. However\, most social
network analysis ignores the problem of missing d
ata by including only actors with complete observ
ations. In this talk we address the modeling of n
etworks with missing data\, developing previous id
eas in missing data\, network modeling\, and netw
ork sampling. We show the value of the mean value
parametrization to study differences between mode
ling approaches. We also develop goodness-of-fit
techniques to better understand model fit. The ide
as are motivated by an analysis of a friendship n
etwork from the National Longitudinal Study of Ad
olescent Health. The work presented is by Krista J
. Gile and Mark S. Handcock.
