That's a good (and very common) question! The quick answer is "yes"..

For a more comprehensive answer I would refer you two resources:

1. A web-seminar that discusses "selecting the right distribution":
https://crystalball.on.intercall.com/confmgr/view_stored_doc.jsp?docId=95131
499264323014082439831328

2. A free training tool that also discusses how to select the right
distribution: http://www.vosesoftware.com/mafree_update/MACB.EXE

Hope this helps!

I just wanted to know if there are any conventions to choose a kind of
distribution.
