Registers new boundary intervals.
The boundaries are the points of the real number line which divide the whole interval into sub-intervals in which members of a data set can be assigned.
Lets assume for example that we have the data set {1.4, 2.4, 2,5, 2.0, 1.5}
,
and we have the boundary set of {0, 1, 2, 3}
. Now if you use the convention of an
open left boundary then this boundary set will divide the interval into the sub-intervals
(-infinity, 0]
, (0,1]
(i.e. the interval from 0
, to
1
which does include 0
, but does not include 1
),
(1,2]
, (2,3]
. Now the values of the data set which belong to each
of these intervals are as follows:
(-infinity, 0]
interval has no data set elements.
(0, 1]
interval has no elements from the data set.
(1, 2]
interval has the elements 1.4, 1.5, 2.0;
from the data set.
(2, 3]
interval has the elements 2.4, 2.5;
from the data set.
