lmekin.object {coxme} | R Documentation |
This class of object is returned by the lmekin
function to
represent a fittd mixed effect linear model.
Objects of this class currently have methods for print
and
residuals
.
The random effects are modeled internally as N(0, s^2A) where s^2 is the residual variance.
The parameters of vcoef
refer to A. THe printed results
for the model have been multiplied by s, removing the
factorization.
The variance matrix vvar
is for the transformed parameters.
For the details of the transformation see the individual variance
functions. The coxmeFull
routine, for instance, uses a log
transform for variances. Use this with caution.
