Protected Attributes
RV	rv
	Random variable of the posterior.

virtual void BM::bayes

(

const vec &

dt

[pure virtual]

Parameters:

dt

vector of input data

Implemented in ARX, Kalman< sq_T >, KalmanCh, EKFfull, EKF< sq_T >, EKFCh, PF, MPF< BM_T >, MixEF, BMEF, multiBM, EKFfixed, Kalman< ldmat >, Kalman< chmat >, and Kalman< fsqmat >.

virtual double BM::logpred

(

const vec &

dt

)

const [inline, virtual]

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 logpred_m().

virtual BM* BM::_copy_

(

bool

changerv = false

)

[inline, virtual]

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, and BMEF.
