An observation bound below by 5 standard deviations is at best a one in a million on a standard normal distribution.

An observation bound below by 5 standard deviations is at best a one in a million on a standard normal distribution.
- FabHK 5y agoYes, for a normal, which is known to have extremely thin tails (decaying with a squared exponential!). Chebyshev's bound holds for any possible distribution (with finite variance).
- FabHK 5y agoNot squared exponential (that's just an exponential), but exponential of a square, even. Anyway.
