I also prefer this python code to the SAS example listed. I have been trying to brush up on statistics over the last couple of years and I think this article points to an issue that occurred to me. Namely that when somebody says they "know statistics" it sort of has to mean that they know one of the big stats packages out there. It doesn't appear that anybody is really doing stats from first principles anymore. It seems like there are differences in terminology between one author and another and now with the different programing models there is a whole new level of incompatibility.
