Calculate lmeStruct Fitted Values
The fitted values at level i are obtained by adding together the population fitted values (based only on the fixed effects estimates) and the estimated contributions of the random effects to the fitted values at grouping levels less or equal to i. The resulting values estimate the best linear unbiased predictions (BLUPs) at level i.
## S3 method for class 'lmeStruct' fitted(object, level, conLin, lmeFit, ...)
object |
an object inheriting from class |
level |
an optional integer vector giving the level(s) of grouping
to be used in extracting the fitted values from |
conLin |
an optional condensed linear model object, consisting of
a list with components |
lmeFit |
an optional list with components |
... |
some methods for this generic accept other optional arguments. |
if a single level of grouping is specified in level
,
the returned value is a vector with the fitted values at the desired
level; else, when multiple grouping levels are specified in
level
, the returned object is a matrix with
columns given by the fitted values at different levels.
This method function is generally only used inside lme
and
fitted.lme
.
