Hello all, I am using lme4 to fit some mixed logistic regressions. I need to impose an identification constraint of the following form:
(1 sig12) (sig12 sig22) and have not figured out how to do it, i.e., sig11 = 1 but the rest of the parameters are free to vary. Is this possible and, if so, how? I've been looking through the archive and help to no avail, but perhaps I'm just missing something. Thanks for any help, Jay -- JVVerkuilen.
