pdCompSymm Object Coefficients
Usage
coef(object, unconstrained)
Arguments
object
|
an object inheriting from class pdCompSymm ,
representing a positive-definite matrix with compound symmetry
structure.
|
unconstrained
|
a logical value. If TRUE the coefficients
are returned in unconstrained form (the same used in the optimization
algorithm). If FALSE the standard deviation and the
correlation coefficient of the compound symmetry of
positive-definite matrix represented by object are
returned. Defaults to TRUE .
|
Description
This method function extracts the coefficients associated with the
positive-definite matrix represented by object
