Member Function Documentation

void BMEF::bayes

(

const vec &

dt

)

[virtual]

Incremental Bayes rule.

Parameters:

dt

vector of input data

Implements BM.

Reimplemented in ARX, and multiBM.

References bayes().

virtual double BM::logpred

(

const vec &

dt

)

const [inline, virtual, inherited]

Evaluates predictive log-likelihood of the given data record I.e. marginal likelihood of the data with the posterior integrated out.

Reimplemented in ARX, MixEF, and multiBM.

virtual BM* BM::_copy_

(

bool

changerv = false

)

[inline, virtual, inherited]

Copy function required in vectors, Arrays of BM etc. Have to be DELETED manually! Prototype: BM* _copy_(){BM Tmp*=new Tmp(this*); return Tmp; }

Reimplemented in ARX.

Referenced by MixEF::MixEF().
