[R-sig-ME] Question on the glmer function of the lme4 R package

[ONKELINX, Thierry]

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?

Best regards,

Thierry

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.

Onderwerp: [R-sig-ME] Question on the glmer function of the lme4 R package

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.

Best regards


 Dr Feddag
