| void | setrvcinrv (const RV &rvc, Array< ivec > &rvcind) |
| Function fills Array by indeces of mpdfs inside given rv. | |
| virtual void | condition (const vec &cond) |
Update ep so that it represents this mpdf conditioned on rvc = cond. | |
| virtual double | evalcond (const vec &dt, const vec &cond) |
| Shortcut for conditioning and evaluation of the internal epdf. In some cases, this operation can be implemented efficiently. | |

Probability density in the form of Chain-rule decomposition: \[ f(x_1,x_2,x_3) = f(x_1|x_2,x_3)f(x_2,x_3)f(x_3) \] Note that
| vec mprod::samplecond | ( | const vec & | cond, | |
| double & | ll | |||
| ) | [inline, virtual] |
Returns the required moment of the epdf.
Returns a sample from the density conditioned on cond,
.
| cond | is numeric value of rv | |
| ll | is a return value of log-likelihood of the sample. |
Reimplemented from mpdf.
