| vec | sample () const |
Returns a sample, from density . | |
| vec | mean () const |
set values of low and high | |
| vec | variance () const |
| return expected variance (not covariance!) | |

Constructors | |
Construction of each epdf should support two types of constructors:
The following constructors should be supported for convenience:
All internal data structures are constructed as empty. Their values (including sizes) will be set by method | |
| void | set_parameters (int dim0) |
Matematical Operations | |
| 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 vec | evallog_m (const Array< vec > &Avec) const |
Compute log-probability of multiple values argument val. | |
| virtual shared_ptr< mpdf > | condition (const RV &rv) const |
| Return conditional density on the given RV, the remaining rvs will be in conditioning. | |
| virtual shared_ptr< epdf > | marginal (const RV &rv) const |
| Return marginal density on the given RV, the remainig rvs are intergrated out. | |
