In the original publication of this article [1], 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.
