Thanks very much Tanja and Joe,
I think these suggestions for sorting will be very useful; we were
trying to
do something similar (but very "hacker-ish") and with this
theoretical basis
I'm sure we'll pull it off.
And for BD, the time transformation should be perfect.
It is a very useful tool. If people cite it, they should
check Bruce Rannala's paper to see if it is there too.
Some closely-related math certainly is.
One thing that computing the transformation for various
values of B and D (birth and death rates, called lambda
and mu in the derivation in my book) is that it gives you
a direct idea of how many groups "born" at each time
are missing from the tree owing to having gone extinct
before reaching the present day.
