Very good, thank you
I was looking for this. I just bumped recently again into Owen's T for
After a first look:
I would outsource _tOwen into a standalone function, since it might
also be useful in other places. scipy.special might also be a good
location for this function, if the implementation is not specific to
the current usage.
