de Moivre-Laplace Theorem

The asymptotic form of the -step Bernoulli distribution with parameters  and  is given by

			(1)
			(2)

(Papoulis 1984, p. 105).

Uspensky (1937) defines the de Moivre-Laplace theorem as the fact that the sum of those terms of the binomial series of  for which the number of successes  falls between  and  is approximately

(3)

where

			(4)
			(5)
			(6)

More specifically, Uspensky (1937, p. 129) showed that

(7)

where the error term satisfies

(8)

for  (Uspensky 1937, p. 129; Kenney and Keeping 1951, pp. 36-37). Note that Kenney and Keeping (1951, p. 37) give the slightly smaller denominator .

A corollary states that the probability that  successes in  trials will differ from the expected value  by more than  is , where

(9)

with

(Kenney and Keeping 1951, p. 39). Uspensky (1937, p. 130) showed that  is given by

(11)

where

and the error term satisfies

(15)

for  (Uspensky 1937, p. 130; Kenney and Keeping 1951, pp. 40-41).
