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.

Value

a vector with the coefficients corresponding to object.
