Extra scale term in normalizing constant? #17
Description
Hello,
I have a question about the implementation of the normalizing constant of the von Mises Fisher distribution. Digging into the code, I saw that the normalizing constant seems to be computed here:
which seems to have an extra scale term (in the third term of the output) compared to what I found in the paper:
Could you help me understand where this scaling term comes from?
Many thanks!
