The addition or subtraction of 0.5 when a discrete distribution, taking only integer values, is used to approximate a continuous distribution, so as to improve the agreement between the two distributions.
A correction term used when the distribution of a discrete random variable is approximated by that of a continuous random variable. For a discrete random variable, X, taking values…, x−1, x, x+1,…, the probability of X taking the value x would be approximated by
where Y is the approximating continuous random variable. See also binomial distribution; poisson distribution; two-by-two table.
