pdDiag Object Coefficients
Usage
coef(object, unconstrained)
Arguments
object
|
an object inheriting from class pdDiag ,
representing a positive-definite matrix with diagonal structure.
|
unconstrained
|
a logical value. If TRUE the logarithm of
the standard deviations corresponding to the variance-covariance
matrix represented by object are returned. If FALSE the
standard deviations are returned. Defaults to TRUE .

Description
This method function extracts the coefficients associated with the
positive-definite matrix represented by object
