List of all members.

## Public Member Functions
| eprod (const Array< const epdf * > epdfs0)
vec | mean () const
| return expected value
vec | variance () const
| return expected variance (not covariance!)
vec | sample () const
| Returns a sample, from density .
double | evallog (const vec &val) const
| Compute log-probability of argument `val`.
const epdf * | operator() (int i) const
| access function
| ~eprod ()
| Destructor.
virtual mat | sample_m (int N) const
| Returns N samples from density .
virtual vec | evallog_m (const mat &Val) const
| Compute log-probability of multiple values argument `val`.
virtual mpdf * | condition (const RV &rv) const
| Return conditional density on the given RV, the remaining rvs will be in conditioning.
virtual epdf * | marginal (const RV &rv) const
| Return marginal density on the given RV, the remainig rvs are intergrated out.
const RV & | _rv () const
| access function, possibly dangerous!
void | _renewrv (const RV &in_rv)
| modifier function - useful when copying epdfs
## Protected Attributes
Array< const epdf * > | epdfs
| Components (epdfs).
Array< datalink_e2e * > | dls
| Array of indeces.
RV | rv
| Identified of the random variable.
