cov.u {eba} | R Documentation |
Computes the (normalized) covariance matrix of the utility scale from the covariance matrix of elimination-by-aspects (EBA) model parameters.
cov.u(object, norm = "sum")

an object of class |
norm |
either |
The additivity rule for covariances
cov(x + y, z) = cov(x, z) + cov(y, z)
is used for the computations.
If norm
is not NULL
, the unnormalized covariance matrix is
transformed using a^2 cov(u)
, where the constant a
results from
the type of normalization applied.
The (normalized) covariance matrix of the utility scale.
