public class IntervalDDNode
extends DiscreteDecisionNode
implements NumericDiscreteNode

Interval discrete decision node. Each state of an IntervalDDNode represents an interval.


Constructor Summary
IntervalDDNode(DiscreteNode node)
          Constructs a new IntervalDDNode object corresponding to the given DiscreteNode object node.
IntervalDDNode(NetworkModel belongsTo)
          Constructs a new IntervalDDNode.
 
Method Summary
 double getQuantile(double probability)
          Returns the quantile corresponding to the specified probability argument of the inverse cumulative distribution function.
 int getStateIndex(double value)
          Returns the index of the state (interval) matching the specified value.
 double getStateValue(int s)
          Returns the low value of the interval associated with state s.
 void setStateValue(int s, double v)
          Sets the low value of the interval associated with state s to v.

Constructor Detail

IntervalDDNode

public IntervalDDNode(NetworkModel belongsTo)
               throws ExceptionHugin
Constructs a new IntervalDDNode.

Throws:
ExceptionHugin

IntervalDDNode

public IntervalDDNode(DiscreteNode node)
               throws ExceptionHugin
Constructs a new IntervalDDNode object corresponding to the given DiscreteNode object node. (node must be a chance or a decision node.) The new object will be identical to node (that is, same parents, same table, etc.) except for its type.

As a side-effect, the object node dies (that is, becomes "not-alive"). Moreover, all (output and temporal) clones associated with node also die.

Throws:
ExceptionHugin
Method Detail

getStateValue

public double getStateValue(int s)
                     throws ExceptionHugin
Returns the low value of the interval associated with state s. To indicate the right endpoint of the rightmost interval, specify s equal to the number of states of this.

Specified by:
getStateValue in interface NumericDiscreteNode
Parameters:
s - the index of the state in question.
Throws:
ExceptionHugin

getStateIndex

public int getStateIndex(double value)
                  throws ExceptionHugin
Returns the index of the state (interval) matching the specified value. If there is no interval containing the specified value, -1 is returned.

Specified by:
getStateIndex in interface NumericDiscreteNode
Parameters:
value - an interval containing this value will be searched for
Returns:
the index of the state (interval) containing the specified value.
Throws:
ExceptionHugin

setStateValue

public void setStateValue(int s,
                          double v)
                   throws ExceptionHugin
Sets the low value of the interval associated with state s to v. To indicate the right endpoint of the rightmost interval, specify s equal to the number of states of this.

Specified by:
setStateValue in interface NumericDiscreteNode
Parameters:
s - the index of the state in question.
v - the new value for state s.
Throws:
ExceptionHugin

getQuantile

public double getQuantile(double probability)
                   throws ExceptionHugin
Returns the quantile corresponding to the specified probability argument of the inverse cumulative distribution function.

Specified by:
getQuantile in interface NumericDiscreteNode
Throws:
ExceptionHugin
