Method Detail

getMean

public Matrix getMean()

Description copied from interface: CentralMomentsGettable

This method returns the first central moment, i.e. the mean vector, of the random variable.

Specified by:

getMean in interface CentralMomentsGettable

Returns:

a Matrix instance

getVariance

public Matrix getVariance()

Description copied from interface: CentralMomentsGettable

This method returns the second central moment, i.e. the variance-covariance matrix, of the random variable.

Specified by:

getVariance in interface CentralMomentsGettable

Returns:

a Number instance

isParametric

public boolean isParametric()

Description copied from interface: Distribution

This method returns true if the distribution is parametric or false otherwise.

Specified by:

isParametric in interface Distribution

Returns:

a boolean

isMultivariate

public boolean isMultivariate()

Description copied from interface: Distribution

This method returns true if the GaussianFunction instance is multivariate.

Specified by:

isMultivariate in interface Distribution

Returns:

a boolean

getType

public Distribution.Type getType()

Description copied from interface: Distribution

This method returns the type of the distribution.

Specified by:

getType in interface Distribution

Returns:

a Type enum

getRandomRealization

public Matrix getRandomRealization()

Description copied from interface: Distribution

This method draws a random realization from the distribution.

Specified by:

getRandomRealization in interface Distribution

Returns:

the observation in a Matrix instance

setLowerBoundValue

public void setLowerBoundValue(Matrix lowerBoundValue)

Description copied from interface: BoundedDistribution

This method sets the lower bound. To remove the bound, just set it to null which is the default value.

Specified by:

setLowerBoundValue in interface BoundedDistribution

Parameters:

lowerBoundValue - a Matrix instance

setUpperBoundValue

public void setUpperBoundValue(Matrix upperBoundValue)

Description copied from interface: BoundedDistribution

This method sets the lower bound. To remove the bound, just set it to null which is the default value.

Specified by:

setUpperBoundValue in interface BoundedDistribution

Parameters:

upperBoundValue - a Matrix instance

getLowerBound

public BasicBound getLowerBound()

getUpperBound

public BasicBound getUpperBound()
