many thanx i appreciate your help, but i concern about Glynn and Wakefield model, and i want to use the lmer function to perform this model and estimate the parameters of the attached model (18)
I'm sorry, but this is a little bit too much for me to handle right now. I don't have any background on a "Glynn and Wakefield" model is: I found this http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2801082/ (Glynn, Wakefield, Handcock, and Richardson 2008) which seems very close but not identical to the JPGs you included (note that the mailing list strips most attachments). Maybe they published a book chapter closely related to their paper? Good luck.

Dear lmer() friends, I amtrying to estimate a model about regress deviance y on deviance x Doesanyone of you has already done this before using lmer() method? i want the code of this model Thanksa lot mervat
transcribing your equation into TeX format:
(y_{ij} - \bar y_{.j}) = \beta(x_{ij}-\bar x_{.j}) + e_{ij} - \bar
e_{.j}
It's not really clear to me what you want to do. It looks like it
*might* be a random_slope model. In other words,
y ~ x + (x|f)
where x is a continuous covariate and f is a grouping variable
(factor) gives
y_{ij} = beta_0 + beta_1*x + (b_{0j} + b_{1j}*x)
Where b_{0j} is a group-level deviate from the intercept and
b_{1j} is a group-level deviation from the slope.
Is that translatable into your context?
Depending on how you want your results presented, van de Pol and
Wright 2009 might be useful:
