In that case, you really should have stopped for a moment to think about 
whether hat you're trying to do actually can be done at all, with any 
useful degree of reliability.

If you don't have any idea what function those data might be supposed to 
follow, then the thing you asked for:

is not defined, and any method you come up with to compute it has to be, 
by definition, incorrect.
