Fitted lme Object
An object returned by the
lme function, inheriting from class
lme and representing a fitted linear mixed-effects
model. Objects of this class have methods for the generic functions
The following components must be included in a legitimate

random, where the first is a vector containing the estimated
fixed effects and the second is a list of matrices with the estimated
random effects for each level of grouping. For each matrix in the
random list, the columns refer to the random effects and the
rows to the groups.
N - the number of observations in
Q - the number of grouping levels,
the number of random effects at each level from innermost to
outermost (last two values are equal to zero and correspond to the
fixed effects and the response),
ngrps - the number of groups
at each level from innermost to outermost (last two values are one
and correspond to the fixed effects and the response), and
ncol - the number of columns in the model matrix for each
level of grouping from innermost to outermost (last two values are
equal to the number of fixed effects and one).
specifying the denominator degrees of freedom for, respectively,
t-tests for the individual fixed effects and F-tests for the
fixed-effects terms in the models.
