## Member Function Documentation

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

Returns the required moment of the epdf.

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

Parameters:

  | cond | is numeric value of `rv`
  | ll | is a return value of log-likelihood of the sample.

Reimplemented in mprod.

virtual mat mpdf::samplecond_m | ( | const vec & | cond,
|  | vec & | ll,
|  | int | N |
| ) |  |  | `[inline, virtual]`

Returns.

Parameters:

  | N | samples from the density conditioned on `cond`, .
  | cond | is numeric value of `rv`
  | ll | is a return value of log-likelihood of the sample.
