Usage
lm.gls(formula, data, W, subset, na.action, inverse = FALSE,
method = "qr", model = FALSE, x = FALSE, y = FALSE,
contrasts = NULL, ...)Arguments
formula
a formula expression as for regression models, of the form
response ~ predictors.
See the documentation of formula for other details.
data
an optional data frame in which to interpret the variables occurring
in formula.
subset
expression saying which subset of the rows of the data should be used
in the fit. All observations are included by default.
na.action
a function to filter missing data.
inverse
logical: if true W specifies the inverse of the weight matrix: this
is appropriate if a variance matrix is used.
method
method to be used by lm.fit.
model
should the model frame be returned?
x
should the design matrix be returned?
y
should the response be returned?
contrasts
a list of contrasts to be used for some or all of
...
additional arguments to lm.fit.
