In my masters thesis I need to cite from "NIST Special Publication 800-22". We are to use IEEE referencing style and I am using an online LaTeX editor to get this done.
Now that this document I need to refer to is a PDF document, I have no idea what is the type of the document that I should treat it as. Is that okay if I treat it as an article? Or else is there any other type that it should fall under?
