Detailed Description

Estimator for Exponential family.

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.

Referenced by BM::logpred_m().

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::init().
