a list with the following components:
thesholds
a list containing the lower threshold lowthres
marking the difference between the two classes 0
(the fewest occurences) and 0.5
;
and the upper threshold upthres
marking the difference between the
two classes 0.5
and 1
(the most occurences)
surrogate a vector containing the clustering for each observation (as
an ordered factor with the 3 following levels ordered by the number of occurences:
0 < 0.5 < 1
.)
