I've recently read some examples where the author describes a general distribution $f(.)$. It is in the context of describing the distribution of parameters for another function where the parameters of the function and presumably the possible functions can vary across particular applications.
Thus, I understand that $f(.)$ is in some sense a general notation and the dot seems to serve as a place holder for many possible objects.
However, I still feel like my understanding is a little fuzzy.
Thus, my questions are:
- How do you pronounce $f(.)$?
- Can you refer me to, or provide me with, a general description of this notation?
- Is there anything particular that I should understand when reading and applying this notation in the context of distribution functions?
