I was a bit surprised, and am not convinced, by the definitions offered for "stochastic." Here's the entry:

1. Random. 2. Following a random distribution pattern, such that its probability may be analyzed statistically, but not predicted precisely. 3. (Rare) Pertaining to conjecture, speculation.

What I think is missing from all three of these is the element of a stochastic process having a present moment and a built-in mechanism of some kind -- although the concession in definition 2 that such a process "may be analysed statistically" does get a good deal of the way there. (I see that I've used the ambiguous word "moment" above, and my subconscious must be at work here: I think that stochastic has an element of moment, i.e. of inertia or past history, as opposed to total randomness, to it.

See my note on another post re the electron, whose location or velocity can be statistically guessed at, but not nailed down.
