Hello,
I posted recently a question about broken stick (segmented)
regression, and an objective approach for applying this approach to
data. Thanks to Joel Schwartz, John Wallace, Nick Ellis and Stephen
Morris for their fast reply.
-------------
Since there was a discussion on this subject earlier this year, the
archives show it almost all:

Stephen Morris ( morriss@wolsun.agric.nsw.gov.au) provided code.
For a less subjective approach one could try using AIC (Joel
Schwartz)
Thanks very much and best regards
Falk
