Constructor Detail

IntervalDCNode

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


IntervalDCNode

public IntervalDCNode(DiscreteNode node)
               throws ExceptionHugin
Constructs a new IntervalDCNode 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.

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 IntervalDCNode.

Specified by:
getStateValue in interface NumericDiscreteNode
Parameters:
s - index of the state
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 IntervalDCNode.

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
