{synonym}

The coefficient $b$ is the leading relative null-mean discrepancy of a regular <likelihood-ratio test statistic>. It is distinct from the finite-sample divisor $1+b/n$ used in a <Bartlett correction>. Different conventions call either of these a correction factor, so the normalization should always be stated explicitly.
