Details

The men were recruited to live in off-campus (fraternity) housing, rented for them as part of the Michigan Group Study Project supervised by Theodore Newcomb from 1953 to 1956. All were incoming transfer students with no prior acquaintance of one another.

The data set, derived from one in the unreleased netdata package, contains a network list newcomb with 14 networks. Each network is complete and contains two edge attributes:

list("rank")

the preference of the \(i\)th man for the \(j\)th man from 1 through 16, with 1 being the highest preference.

list("descrank")

the same, but 1 indicates lowest preference.
