newfrat: Newcomb, Nordlie Fraternity

In zalmquist/networkdata: Lin Freeman's Network Data Collection

Description

newfrat: Two lists of network objects each with 15 networks.

BACKGROUND These 15 matrices record weekly sociometric preference rankings from 17 men attending the University of Michigan in the fall of 1956; data from week 9 are missing. A "1" indicates first preference, and no ties were allowed.

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.

Usage

data(newfrat)

Details

newfrat: a list object containing newfrat.dich and newfrat.val.

newfrat.val: a list of 16 network objects–however week 9 is missing newfrat.val[[10]]=NA (newfrat.val\$newc9=NA)– each network object is valued.

newfrat.dich: a list of 16 network objects–however week 9 is missing newfrat.val[[10]]=NA (newfrat.val\$newc9=NA)– this item is based off of newfrat.val but has been dichotomized so that there is a tie between i and j if the i,jth cell is less than or equal to 8 and 0 if the i,jth cell is 9 or greater.

newc0: initial time point.
