Under most circumstances, it's my habit to take something I've learned that I find useful and I'm fairly sure I've learned right, find an useful encapsulation boundary, and push that thing I've learned onto CPAN so I don't have to remember the details of how to do it right later.
But doing this with statistics has largely eluded me, except for the some of the most primitive mechanisms to joining data producers to statistics consumers.
Statistics are deeply confusing, and even thought I know they are confusing I still find it hard to make them fit in my head (because implications are often not even predictably confusing to me).
Fortunately, I can console myself that I'm not the only person for which this is the case, but at least I'm avoiding the use of them correctly.
