.
In particular this type of arise by conditioning of a mixture model.
At present the only supported operation is evallogcond().
Public Member Functions | |
| mratio (const epdf *nom0, const RV &rv, bool copy=false) | |
| double | evallogcond (const vec &val, const vec &cond) |
| Shortcut for conditioning and evaluation of the internal epdf. In some cases, this operation can be implemented efficiently. | |
| void | ownnom () |
| Object takes ownership of nom and will destroy it. | |
| ~mratio () | |
| Default destructor. | |
Matematical operations | |
| virtual vec | samplecond (const vec &cond) |
Returns a sample from the density conditioned on cond, . | |
| virtual mat | samplecond_m (const vec &cond, int N) |
| Returns. | |
| virtual void | condition (const vec &cond) |
Update ep so that it represents this mpdf conditioned on rvc = cond. | |
| virtual vec | evallogcond_m (const mat &Dt, const vec &cond) |
| Matrix version of evallogcond. | |

Protected Attributes | |
| const epdf * | nom |
| Nominator in the form of mpdf. | |
| epdf * | den |
| Denominator in the form of epdf. | |
| bool | destroynom |
| flag for destructor | |
| datalink_m2e | dl |

| epdf * | ep |
| pointer to internal epdf | |
Default constructor. By default, the given epdf is not copied! It is assumed that this function will be used only temporarily.
