void bdm::mlnorm< sq_T >::condition | ( | const vec & | cond | ) | `[inline, virtual]`

Set value of `rvc` . Result of this operation is stored in `epdf` use function `_ep` to access it.

Reimplemented from bdm::mpdf.

Reimplemented in bdm::mlstudent.

void bdm::mpdf::from_setting | ( | const Setting & | set | ) | `[inline, virtual, inherited]`

Load from structure with elements:

     { rv = {class="RV", names=(...),}; // RV describing meaning of random variable
       rvc= {class="RV", names=(...),}; // RV describing meaning of random variable in condition
       // elements of offsprings
     }

Reimplemented from bdm::root.

Reimplemented in bdm::mepdf, bdm::mprod, bdm::mgnorm< sq_T >, bdm::mgamma, bdm::migamma_ref, and bdm::mlognorm.

virtual vec bdm::mpdf::samplecond | ( | const vec & | cond | ) | `[inline, virtual, inherited]`

Returns a sample from the density conditioned on `cond`, .

Parameters:

  | cond | is numeric value of `rv`

Reimplemented in bdm::mprod.
