WebIn statistics, the Q-function is the tail distribution function of the standard normal distribution. [1] [2] In other words, is the probability that a normal (Gaussian) random variable will obtain a value larger than standard deviations. Equivalently, is the probability that a standard normal random variable takes a value larger than . WebExponential tail bounds automatically imply moment bounds and vice versa. That is to say, ( a) is equivalent to ( A) for a ∈ { j, k, l } below where X is a nonnegative random variable and ‖ X ‖ p = ( E X p) 1 / p. C, c > 0 are universal constants that may change from line to line. ( j) For all p ≥ 1, ‖ X ‖ p ≤ c σ p.
