Member Function Documentation

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

Returns a sample from the density conditioned on cond, $x \sim epdf(rv|cond)$.

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, inherited]

Returns.

Parameters:
N samples from the density conditioned on cond, $x \sim epdf(rv|cond)$.
cond is numeric value of rv
ll is a return value of log-likelihood of the sample.
