Hi I had not see any answer yet but maybe there is nobody who wants to touch the elusive object of "outlier". Neither me, but here are some ideas how one can proceed.
First of all its always up to you what is considered an outlier and how will you deal with them. I usually call an outlier any item which does not fit to the pattern and the pattern is usually best observed by some plotting function. You can identify outlier points, inspect the data source, correct typing mistakes and only if the value is really measured and you can not find any reason why it has such value it is real outlier. Then ***you*** need to decide what to do with it - discard, can come from some long tailed distribution, ... So here are my 0.02$ regarding an outlier theme.
