Method Details

createData

public void createData(Parameters parameters,
 boolean newModel)

Description copied from interface: Simulation

Creates a data set and simulates data.

Specified by:

createData in interface Simulation

Parameters:

parameters - The parameters to use in the simulation.

newModel - If true, a new model is created. If false, the model is reused.

getDataModel

public DataModel getDataModel(int index)

Description copied from interface: Simulation

Returns the number of data sets to simulate.

Specified by:

getDataModel in interface Simulation

Parameters:

index - The index of the desired simulated data set.

Returns:

That data set.

getTrueGraph

public Graph getTrueGraph(int index)

Description copied from interface: Simulation

Returns the true graph at the given index.

Specified by:

getTrueGraph in interface Simulation

Parameters:

index - The index of the desired true graph.

Returns:

That graph.

getDescription

public String getDescription()

Description copied from interface: Simulation

Returns the description of the simulation.

Specified by:

getDescription in interface Simulation

Returns:

Returns a one-line description of the simulation, to be printed at the beginning of the report.

getParameters

public List<String> getParameters()

Description copied from interface: Simulation

Returns the list of parameters used in the simulation.

Specified by:

getParameters in interface HasParameters

Specified by:

getParameters in interface Simulation

Returns:

Returns the parameters used in the simulation. These are the parameters whose values can be varied.

getNumDataModels

public int getNumDataModels()

Description copied from interface: Simulation

Returns the number of data models.

Specified by:

getNumDataModels in interface Simulation
