How an input series enters the model is called its transfer function. Thus, ARIMA models with input series are sometimes referred to as transfer function models. In the preceding regression and ...

A new set of modified Legendre rational functions which are mutually orthogonal in L2(0, + ∞) is introduced. Various projection and interpolation results using the modified Legendre rational functions ...

This report presents near-minimax rational approximations for the inverse of the error function inverf $x$, for $0 \leqslant x \leqslant 1 - 10^{-10000}$, with ...
