EIES data sets
The Electronic Information Exchange System (EIES) data were collected by Freeman and Freeman (1980). This data set is discussed also in Wasserman and Faust (1994). This is a network of 32 researchers who participated in an early study on the effects of electronic information exchange, a precursor of email communication.
There are two actor-level covariates. The first is the number of citations in a specified period. The second is the discipline of the researcher. It is coded 1 for sociologists (of whom there were 17), 2 for anthropologists (6), 3 for mathematicians and statisticians (3), and 4 for psychologists (6). These covariates are in the file eies.att (att for attributes). The citation number is very skewed, therefore a dichotomized version is used which is available in file eies.atd (which also contains a dichotomized discipline variable).
The two networks are EIES.1
and EIES.2
.
The codes 0-4 have the following meanings.
EIES.att
:
File EIES.atd
is a dichotomized version of EIES.att
.
messages.asc
is the matrix of the number of messages sent between actors.
EIES.paj
is a Pajek file of this data set, constructed by V. Batagelj and
taken from the Pajek website.
