Detailed Description

Optimal importance density for Nonlinear Gaussian SS Models.

Describes the optimal importance density for all systems of the form

\[ x_k = f(x_{k-1}) + v_k, \quad v_k \sim N(0, \Sigma_v) \]

\[ z_k = H x_k + w_k, \quad w_k \sim N(0, \Sigma_w) \]

This means all systems with a system equation that uses a AnalyticConditionalGaussian Class and a measurement equation that uses a LinearAnalyticConditionalGaussian class

virtual SymmetricMatrix BFL::OptimalImportanceDensity::CovarianceGet ( ) const [virtual]

Get the Covariance Matrix E[(x - E[x])^2] of the Analytic pdf.

Get first order statistic (Covariance) of this AnalyticPdf

Returns:
The Covariance of the Pdf (a SymmetricMatrix of dim DIMENSION)
Todo:
extend this more general to n-th order statistic
Bug:
Discrete pdfs should not be able to use this!

Reimplemented from BFL::BFL::Pdf< MatrixWrapper::ColumnVector >.

virtual Matrix BFL::OptimalImportanceDensity::dfGet ( int  i) const [virtual]
virtual ColumnVector BFL::OptimalImportanceDensity::ExpectedValueGet ( ) const [virtual]

Get the expected value E[x] of the pdf.

Get low order statistic (Expected Value) of this AnalyticPdf

Returns:
The Expected Value of the Pdf (a ColumnVector with DIMENSION rows)
Note:
No set functions here! This can be useful for analytic functions, but not for sample based representations!
For certain discrete Pdfs, this function has no meaning, what is the average between yes and no?

Reimplemented from BFL::BFL::Pdf< MatrixWrapper::ColumnVector >.
