Package Localiser.algorithms.locErrors

Class LikilihoodError

java.lang.Object

Localiser.algorithms.locErrors.EllipticalError

Localiser.algorithms.locErrors.LikilihoodError

All Implemented Interfaces:

LocaliserError

public class LikilihoodError
extends EllipticalError

Errors are generated from the curvature of a Chi2 surface. Saves the error as an ellipse. Thus, once saved some information will be lost.

Method Details

getError

public double getError(PamVector errorDirection)

Description copied from interface: LocaliserError

Return the error in a particular direction. The direction is based on the 3D Cartesian co-ordinate grid the localisation took place in.

Specified by:

getError in interface LocaliserError

Overrides:

getError in class EllipticalError

Parameters:

errorDirection - - the direction of the error to find

Returns:

the value of the error in the direction specified.

logLikelihood

public double logLikelihood(double[] location)

The log likilihood.

Parameters:

location - - the point on the chi2 surface to fin dlog likilhood for.

Returns:

the log likilihood.
