This operator transforms a vote proportion variable into an
uncontestedness variable. Thus, if vote88 is the Democratic proportion of the
two-party vote, UNC!vote88 takes on the values
for Republican uncontested,
0 for contested seats, and 1 for Democratic uncontested. Default values for
each of these are vote88
0.05, 0.05
vote88
0.95, and vote88
0.95,
respectively; these defaults can be changed with the UNC command.
