Modifier and Type	Method	Description
Normal	getDistribution(double evaluationPoint)
final double	getExpected()	Equivalent to calling RandomProcess.getDistribution(double) with argumant 1.0, and then Distribution.getExpected().
final double	getLowerConfidenceQuantile(double confidence)	The same thing can be achieved by first calling RandomProcess.getDistribution(double) with argumant 1.0, and then ContinuousDistribution.getQuantile(double) (but with different input argument).
final double	getStandardDeviation()	Equivalent to calling RandomProcess.getDistribution(double) with argumant 1.0, and then Distribution.getStandardDeviation().
final double	getUpperConfidenceQuantile(double confidence)	The same thing can be achieved by first calling RandomProcess.getDistribution(double) with argumant 1.0, and then ContinuousDistribution.getQuantile(double) (but with different input argument).

Method Details

getDistribution

public Normal getDistribution(double evaluationPoint)

Specified by:

getDistribution in interface RandomProcess<Normal>

Parameters:

evaluationPoint - How far into the future?

Returns:

The distribution for the process value at that future time.

getValue

public double getValue()

setValue

public void setValue(double newValue)

step

public double step(double stepSize,
 double standardGaussianInnovation)

simulate

public RandomProcess.SimulationResults simulate(int numberOfRealisations,
 int numberOfSteps,
 double stepSize)

Description copied from interface: RandomProcess

Returns an collection of sample sets. The array has numberOfSteps elements, and each sample set has numberOfRealisations samples.

Returns:

An array of sample sets. The array has aNumberOfSteps elements, and each sample set has aNumberOfRealisations samples.

getExpected

public final double getExpected()

Equivalent to calling RandomProcess.getDistribution(double) with argumant 1.0, and then Distribution.getExpected().

getLowerConfidenceQuantile

public final double getLowerConfidenceQuantile(double confidence)

The same thing can be achieved by first calling RandomProcess.getDistribution(double) with argumant 1.0, and then ContinuousDistribution.getQuantile(double) (but with different input argument).

getStandardDeviation

public final double getStandardDeviation()

Equivalent to calling RandomProcess.getDistribution(double) with argumant 1.0, and then Distribution.getStandardDeviation().

getUpperConfidenceQuantile

public final double getUpperConfidenceQuantile(double confidence)

The same thing can be achieved by first calling RandomProcess.getDistribution(double) with argumant 1.0, and then ContinuousDistribution.getQuantile(double) (but with different input argument).

getVariance

public final double getVariance()

Equivalent to calling RandomProcess.getDistribution(double) with argumant 1.0, and then Distribution.getVariance().
