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.
USAGE:
fitted(object, level, asList, type)
REQUIRED ARGUMENTS:
object
an object inheriting from class
glme,
representing a fitted linear mixed-effects model.
level
an optional integer vector giving the level(s) of grouping
to be used in extracting the fitted values
from
object.
Level values increase from outermost to innermost grouping,
with level zero corresponding to the population fitted values.
Defaults to the highest or innermost level of grouping.
asList
an optional logical value.
If
TRUE and a single value is given
in
level,
the returned object is a list with the fitted values split by groups;
else the returned value is either a vector or a data frame,
according to the length of
level.
Defaults to
FALSE.
type
an optional character string indicating the type of fitted
values to be extracted from the
glme fit,
with choices
"response"
and
"link".
Partial matching of arguments is used,
so only the first character needs to be provided.
Default is
"response".
VALUE:
If a single level of grouping is specified
in
level,
the returned value is either a list with the fitted values split by groups
(
asList=TRUE)
or a vector with the fitted values (
asList=FALSE);
else, when multiple grouping levels are specified
in
level,
the returned object is a data frame with columns given
by the fitted values at different levels
and the grouping factors.
