I had a look at the other modules under Bio. There are a couple of supervised 
learning routines there, but they wouldn't fit well as part of a Bio.Statistics 
module. However, there are a couple of other statistics-related routines that 
would be nice to have in Biopython (e.g. routines to estimate probability 
density functions or alternative non-parametric regression models). So I would 
argue for a Bio.Statistics module containing the Lowess function for now and 
hopefully other routines later, but keep the existing modules under Bio where 
they are.
