\end{ldescription}
\end{Arguments}
\begin{Details}\relax

\code{-Inf} or \code{Inf} return logits of 0 or 1 respectively.  Any \code{NA}s in the input 
will also be \code{NA}s in the output.
\end{Details}
\begin{Value}
An object of the same type as \code{x} containing the inverse logits of the
input values.
