A continuity correction used in certain problems in mathematical statistics (e.g. in the problem of testing statistical independence). It is used to improve the approximation by a -distribution of the -test statistic (cf. also Chi-squared distribution; Chi-squared test). It was proposed by J. Yates [1].
