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.
