Why close? If anything it could be community wiki. – Ryogi Oct 29 '11 at 17:42

I would rephrase the question in something like: What probability distributions are commonly used, what are their properties and what are their applications. The problems with that are: it depends on your field, the particular model etc. and it's probably better explained on Wikipedia. – Bob Jansen Oct 29 '11 at 17:57
Certainly off-topic as it's currently phrased. Asking about the "most popular" is inappropriate on any StackExchange site... – Shane Oct 29 '11 at 19:03

It would be much better to rephrase this as a series of specific questions on the major distributions (normal, Poisson, Weibull, Levy-stable, Pareto, etc.). – Tal Fishman Oct 29 '11 at 23:00

BTW, the answer to your question is in chapter 6 of Wilmott's FAQ in Quantitative Finance. – Tal Fishman Nov 1 '11 at 19:33

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
