cov.u.Rd
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")
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 a2cov(u), where the constant a results from
the type of normalization applied.
The (normalized) covariance matrix of the utility scale.
