coef.corStruct: Coefficients of a corStruct Object
Description
This method function extracts the coefficients associated with the
correlation structure represented by object.
Usage
coef(object, unconstrained)
coef(object) <- value
Arguments
object
an object inheriting from class corStruct,
representing a correlation 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", possibly constrained, form. Defaults to
value
a vector with the replacement values for the coefficients
associated with object. It must be a vector with the same length
of coef{object} and must be given in unconstrained form.
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. Object must be initialized (using
initialize) before new values can be assigned to its
coefficients.
