public interface DataModel
extends KnowledgeTransferable, VariableSource

Interface implemented by classes, instantiations of which can serve as data models in Tetrad. Data models may be named if desired; if provided, these names will be used for display purposes.

This interface is relatively free of methods, mainly because classes that can serve as data models in Tetrad are diverse, including continuous and discrete data sets, covariance and correlation matrices, graphs, and lists of other data models. So this is primarily a taqging interface.

Method Details

getName

String getName()

getName.

Returns:

the name of the data model (may be null).

setName

void setName(String name)

Sets the name of the data model (may be null).

Parameters:

name - the name to set

toString

String toString()

Renders the data model as as String.

Overrides:

toString in class Object

Returns:

a String object

isContinuous

boolean isContinuous()

Returns:

true if the data model is continuous, false otherwise.

isDiscrete

boolean isDiscrete()

isDiscrete.

Returns:

true if the data model is discrete, false otherwise.

isMixed

boolean isMixed()

isMixed.

Returns:

true if the data model is mixed continuous/discrete, false otherwise.

getVariable

Node getVariable(String name)

getVariable.

Parameters:

name - a String object

Returns:

the variable with the given name, or null if no such variable exists.

copy
