What about the Qs? (complements)
In other words, 1 - P. Right? One response is why do you need to define it, given how easy it is to get from the cumulative density function?
If not, use a common name for it. Unfortunately, I don't have a good suggestion.
Perhaps not really needed? Is there an accuracy reason for both?
It depends how accurate you want to be: calculating 1-P incurs cancellation error if P is very near 1, where as for most (all?) distributions we can calculate Q directly without the subraction from unity.
Here's a first stab (I'm sure it can be improved):
class StudentsT {
I think the "Boostified" name would be in all lower case: students_t or whatever. John.
