| lmList4-class {lme4} | R Documentation |
Class "lmList4" is an S4 class with basically a
list of objects of class lm with a common
model (but different data); see lmList() which returns
these.
Package nlme's lmList() returns objects of
S3 class "lmList" and provides methods for them, on which our
methods partly build.
Objects can be created by calls of the form
new("lmList4", ...) or, more commonly, by a call to
lmList().
A dozen methods are provided. Currently, S4
methods for show, coercion (as(.,.)) and
others inherited via "list", and S3 methods for
coef, confint, fitted,
fixef, formula, logLik,
pairs, plot, predict,
print, qqnorm, ranef,
residuals, sigma, summary,
and update.
returns the standard deviation
σ-hat (of the errors in the linear models), assuming a
common variance σ^2 by pooling (even when
pool = FALSE was used in the fit).
