Normal distribution tail bound
Web9 de dez. de 2010 · Bounding Standard Gaussian Tail Probabilities. We review various inequalities for Mills' ratio (1 - \Phi)/\phi, where \phi and \Phi denote the standard Gaussian density and distribution function, respectively. Elementary considerations involving finite continued fractions lead to a general approximation scheme which implies and refines … WebRemarkably, the Cherno bound is able to capture both of these phenomena. 4 The Cherno Bound The Cherno bound is used to bound the tails of the distribution for a sum of independent random variables, under a few mild assumptions. Since binomial random variables are sums of independent Bernoulli random variables, it can be used to bound (2).

It is especially useful for sums of independent …
