\subsection{Detailed Description}
(Approximate) Student t density with linear function of mean value

The internal \hyperlink{classbdm_1_1epdf}{epdf} of this class is of the type of a Gaussian (\hyperlink{classbdm_1_1enorm}{enorm}). However, each conditioning is trying to assure the best possible approximation by taking into account the zeta function. See \mbox{[}\mbox{]} for reference.

Perhaps a moment-matching technique? \subsection*{Public Member Functions}
