This method function extracts the coefficients associated with the
variance function structure represented by object.
Usage
coef(object, unconstrained, allCoef)
coef(object) <- value
Arguments
object
an object inheriting from class varFunc
representing a variance function structure.
unconstrained
a logical value. If TRUE the coefficients
are returned in unconstrained form (the same used in the optimization
algorithm). If FALSE the coefficients are returned in
"natural", generally constrained form. Defaults to
allCoef
a logical value. If FALSE only the coefficients
which may vary during the optimization are returned. If TRUE
all coefficients are returned. Defaults to FALSE.
value
a vector with the replacement values for the coefficients
associated with object. It must be have the same length of
coef{object} and must be given in unconstrained
form. Object must be initialized before ne
Value
a vector with the coefficients corresponding to object.
SIDE EFFECTS
On the left side of an assignment, sets the values of the coefficients
of object to value.
