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)

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:
