[R-sig-ME] Mixed effect model with lme4

[Sijia Huang]

Hi everyone,

I am trying to fit a mixed effect model using lme4. The random effect part
of the model is kind of tricky:

delta_{1s}*(alpha_i + beta_i * d_{t=0,i=1})

In which *delta_1s* is the random effect and are multiplied by the
quantities in the parentheses. The *alpha_i* and *beta_i* are parameters
that need to be estimated, while the d_t=0,i=1 is a dummy variable.

I wonder if this model can be specified with lme4 syntax. Thank you!


Best,
Sijia
