BMC Medical Research Methodology volume 20, Article number: 82 (2020)
Correction to: BMC Med Res Methodol
In the original publication of this article , there is a small calculational error in the illustrative example. The estimated second preference contrast Δπ' should be -3.23, not -0.49 as shown. All the other numerical results in the example are shown correctly. This change does not materially affect the substantive interpretation of the analysis.
