	\paragraph{Syntax}
 
 \begin{verbatim}
 Y = wmean(X,RANGE,BETA)
 \end{verbatim}
 \paragraph{Input arguments}
 
 \begin{itemize}
 \item
   \texttt{X} {[} tseries {]} - Input tseries object whose data will be
   averaged column by column.
 \item
   \texttt{RANGE} {[} numeric {]} - Date range on which the weighted
   average will be computed.
 \item
   \texttt{BETA} {[} numeric {]} - Discount factor; the last observation
   gets a weight of of 1, the N-minus--1st observation gets a weight of
   \texttt{BETA}, the N-minus--2nd gets a weight of \texttt{BETA\^{}2},
   and so on.
 \end{itemize}
 \paragraph{Output arguments}
 
 \begin{itemize}
 \item
   \texttt{Y} {[} numeric {]} - Array with weighted average of individual
   columns; the sizes of \texttt{Y} are identical to those of the input
   tseries object in 2nd and higher dimensions.
 \end{itemize}
