[R-sig-ME] [Fwd: Re: gls/lme/lmer Likelihood]

[Andrzej Galecki]

Hello,

logLik function appears to return gls/lme/lmer log-likelihood evaluated for a
model at:

1. the set of  estimated coefficients
  and
2. for the data set, to which the model was fitted.

I am wondering whether there is a simple/elegant way to return the
log-likelihood for the same model evaluated at:

1. a given set of parameter values _other_ than the estimated coefficients
 and
2. for a different data set ?

Respectfully,

Andrzej
