Jan 21, 2016 at 4:06 comment added Grk58 I want to see how to approach this very generic problem from the statistician point of view (which I'm obviously not). In other words, I'd like to order a sandwich without listing every ingredient, relying on your, chefs, expertise.
Jan 21, 2016 at 4:04 comment added Grk58 I am a high-school dropout, so Poisson - yeah, homogenous - yeah. No natural starting point - observation can start at any time. Since there's no answer from frequentist point of view, let's see Bayesian. Don't have any priors, and hope to stay that way :)

Jan 21, 2016 at 0:08 comment added gung - Reinstate Monica I don't think this is answerable at present. Are you thinking of something like a Poisson process? If so, is it homogenous? Is day 0 some kind of natural starting point (say when the most event occurred? Also, are you thinking of this from a Bayesian point of view? (From the frequentist point of view, there isn't such a thing as a "probability that it's rare".) If you want a Bayesian response, what is your prior? Or did you just want to know the probability of finding data as extreme as yours under the assumption it's rare? Etc.
