Social network research has been confined to small groups because large networks are intractable, and no systematic theory of network sampling exists. This paper describes a practical method for sampling average acquaintance volume (the average number of people known by each person) from large populations and derives confidence limits on the resulting estimates. It is shown that this average figure also yields an estimate of what has been called "network density." Applications of the procedure… 

Network Theory and Small Groups

This article describes the network approach to small groups. First, the core constructs that compose social network research are explained. The primary theories that provide the intellectual

Social Network Analysis

This chapter uses a hypothetical dataset to illustrate the utility of social network graphs and measures, both for theory and policy.

Modeling and projection of respondent driven network samples

This report fitted the Exponential Random Graph Model (ERGM) and a Stochastic Block Model (SBM) to an empirical study of the Facebook friendship network and calculated essential network statistics of each sampling method and then compared the result to the original network observed statistics.

Sociology 323: Social networks

This course provides an introduction to social networks. Topics include the small-world puzzle (six degrees of separation), the strength of weak ties, centrality, data collection, and the spread of

The Structure of Undergraduate Association Networks: A Quantitative Ethnography

This paper presents an original network dataset of undergraduate Facebook users and demonstrates the feasibility and acceptability of this form of measurement, and begins a preliminary exploration of Network Homophily and Multiplexity on Facebook.

Estimation in Network Populations

In social networks subjects are linked to one another forming components and structures that are usually of interest. The subjects may have a variable of interest which, in general, can only be

Sampling and inference in complex networks

This thesis focuses on the use of sampling to infer non-trivial properties of the network itself – both structural and functional and introduces a sampling technique, based on concepts from expander graphs, to infer aspects of community structure in the larger network.



Social Structure from Multiple Networks. I. Blockmodels of Roles and Positions

Networks of several distinct types of social tie are aggregated by a dual model that partitions a population while simultaneously identifying patterns of relations. Concepts and algorithms are

The Strength of Weak Ties

Analysis of social networks is suggested as a tool for linking micro and macro levels of sociological theory. The procedure is illustrated by elaboration of the macro implications of one aspect of

Social Structure from Multiple Networks. II. Role Structures

Role structures in small populations are given operational meaning as algebras generated from the sociometric blockmodels of Part I by Boolean multiplication (matrix multiplication employing binary

Transitivity in Structural Models of Small Groups

Our purpose here is to show how various deterministic models for the structure of interpersonal relations in small groups may all be viewed as special cases of a single model: namely, a transitive

Structural inference in organizations

This paper considers the statistical inference of structural properties in organizations. Specifically, the sampling probability distributions of the number of links and the cumulative distribution
