Description: For a given phylogeny on present day data which is
calibrated to calendar-time, a method for estimating maximum
likelihood speciation and extinction processes is provided. The
method accounts for rate changes and mass extinction events:
Time is split into intervals. Throughout an interval, the
speciation and extinction rates stay constant. At the end of an
interval, the speciation and extinction rates may change, and a
fraction of the extant species may become extinct (mass
extinction). No species becoming extinct at the end of an
interval is a rate shift event without mass extinction. The
method estimates the maximum likelihood time intervals, the
speciation and extinction rates in each interval, and the
fraction of species going extinct (unless the fraction is known
and set to a predefined value). Note that the method takes into
account the whole phylogeny, in particular it accounts for the
"pull of the present" effect.
