Friendship
Description
Longitudinal classroom friendship network and behavior (Andrea Knecht)
Usage
data(friendship, package = "SNA4DSData")
Format
friendship is a list of network objects at four time points,
containing friendship nominations of the column node by the row node.
The following values are used: 0 = no, 1 = yes, NA = missing, 10 = not a
member of the classroom (structural zero).
demographics a data frame with 26 rows (the pupils) and four demographic variables about the pupils:
-
sex (1 = girl, 2 = boy)
age (in years)
ethnicity (1 = Dutch, 2 = other, 0 = missing)
religion (1 = Christian, 2 = non-religious, 3 = non-Christian religion, 0 = missing)
primary a 26 x 26 matrix indicating whether two pupils attended the same primary school. 0 = no, 1 = yes
delinquency a data frame with 26 rows (the pupils) and four columns
(the four time steps). It contains the rounded average of four items
(stealing, vandalizing, fighting, graffiti).
Categories: frequency over last three months, 1 = never, 2 = once, 3 = 2–4 times,
4 = 5–10 times, 5 = more than 10 times; 0 = missing.
alcohol a data frame with 26 rows (the pupils) and 3 columns
(waves 2, 3, and 4). It contains data on alcohol use (“How often did you
drink alcohol with friends in the last three months?”).
Categories: 1 = never, 2 = once, 3 = 2–4 times, 4 = 5–10 times,
5 = more than 10 times; 0 = missing.
advice a data frame with one variable, “school advice”, the assessment
given at the end of primary school about the school capabilities of the pupil
(4 = low, 8 = high, 0 = missing)
A list containing four network networks and separate advice,
alcohol, delinquincy, demographics, and primary vectors.
Details
The Knecht dataset contains the friendship network of 26 pupils in a Dutch
school class measured at four time points along with several demographic and
behavioral covariates like age, sex, ethnicity, religion, delinquency,
alcohol consumption, primary school co-attendance, and school advice. Some of
these covariates are constant while others vary over time. The full dataset
(see Knecht 2006 and 2008) contains a large number of classrooms while the
dataset presented here is an excerpt based on one single classroom. This
excerpt was first used in a tutorial for the software Siena and the
corresponding R package RSiena (Snijders, Steglich and van de Bunt 2010). The
following description was largely copied from the original data description
provided on the homepage of the Siena project (see below for the URL). The
data were collected between September 2003 and June 2004 by Andrea Knecht,
supervised by Chris Baerveldt, at the Department of Sociology of the
University of Utrecht (NL). The entire study is reported in Knecht (2008).
The project was funded by the Netherlands Organisation for Scientific
Research NWO, grant 401-01-554. The 26 students were followed over their
first year at secondary school during which friendship networks as well as
other data were assessed at four time points at intervals of three months.
There were 17 girls and 9 boys in the class, aged 11–13 at the beginning of
the school year. Network data were assessed by asking students to indicate up
to twelve classmates which they considered good friends. Delinquency is
defined as a rounded average over four types of minor delinquency (stealing,
vandalism, graffiti, and fighting), measured in each of the four waves of
data collection. The five-point scale ranged from ‘never’ to 'more than 10
times', and the distribution is highly skewed. In a range of 1–5, the mode
was 1 at all four waves, the average rose over time from 1.4 to 2.0, and the
value 5 was never observed.
The data were originally included in the xergm.common package.
The version in the SNA4DSData package has been cleaned and made ready for
use with the btergm package. This includes rhw imputation of NA's and
removal of absent nodes.

The data were gathered by Andrea Knecht, as part of her PhD research,
building on methods developed by Chris Baerveldt, initiator and supervisor of
the project. The project is funded by the Netherlands Organisation for
Scientific Research NWO, grant 401-01-554, and is part of the research
program “Dynamics of Networks and Behavior” with principle investigator
Tom A. B. Snijders.
