Dear all, Could you please help me in the estimation of the different parameters of the Bradley-Terry model with random effects by the glmer function of the lme4 R package. The model, the marginal likelihood and the real data and the main question are described in the attached file.

We need more information to connect your data to the model. What is the interpretation of the subscript i and j and U in connection to your data? How does your dataset look like?
