In the paper, the authors find series expansions and identities for positive integer powers of inverse (hyperbolic) sine and tangent, for composite of incomplete gamma function with inverse hyperbolic ...

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 ...

The sample inverse autocorrelation function (SIACF) plays much the same role in ARIMA modeling as the sample partial autocorrelation function (SPACF) but generally indicates subset and seasonal ...
