\chapter{Future Improvements}

There are several improvements that should be made to RVadd.  These
include the following:

\begin{enumerate}

\item The final screen, a demonstration of the effects of convolution on
different PMFs, needs to be improved.  Allowing for multiples of
one pmf added to multiples of another pmf to show the smoothing effects
of convolution would be useful.

\item The structure of the program could be reorganized to show different
methods of adding random variables as options on the same screen, instead
of clicking to move from screen to screen sequentially.  This would help
show that all the methods did the same thing, and would also improve the
continuity of the application.

\item Making the labels on the program hypertext would be a very useful
improvement, giving an intuitive way to get help in the application.

\end{enumerate}
