%description
Uniform Error Index is the weighted average of different error measures.
Uniform Error Index utilizes output from different error function and
gives more robust and stable error values. This package has been developed
to compute Uniform Error Index from ten different loss function like Error
Square, Square of Square Error, Quasi Likelihood Error, LogR-Square,
Absolute Error, Absolute Square Error etc. The weights are determined
using Principal Component Analysis (PCA) algorithm of Yeasin and Paul
(2024) <doi:10.1007/s11227-023-05542-3>.
