The lifespan is simply the span between the first and
the last timepoint in the IP-table , i.e.
The length of the lifespan,
i.e. the number of chronons, can therefore be calculated as
Partitioning the lifespan uniformly into m segments means that
each segment should comprise
chronons and the breakpoints of the partition P are at that
distance from each other.
A breakpoint pk is determined by
for . This takes into account the possibility that the
ratio in (9.1) might not result in an integer.
Figure 9.2 summarises the algorithm for calculating a
uniform lifespan partition. An example of such a partition is shown
in figure 9.3 for the example scenario that has been used
chapter 5.
