+It is convenient for the (end-)user to refer to the statistics by strings,
+so we specify functions to convert between strings and \code{psStats}:
+\begin{prototype}
+psStats *psStatsFromString(const char *string);
+psString psStatsToString(const psStats *stats);
+\end{prototype}
+\code{psStatsFromString} shall parse the input \code{string} for
+statistics options.  Multiple options may be included in the same
+string, separated by spaces, commas or semi-colons.  The options shall
+be specified by their \code{psStatsOptions} enum, without the leading
+\code{PS_STAT_}.  In addition, \code{SAMPLE_} may be excluded for the
+user's convenience, and \code{ROBUST} shall refer to a
+\code{ROBUST_MEDIAN}, \code{FITTED} to a \code{FITTED_MEAN}, and
+\code{CLIPPED} to a \code{CLIPPED_MEAN}.  \code{psStatsToString} shall
+translate in the reverse direction.
