Constructor Detail

AggregateExpression

public AggregateExpression(Expression frequency,
                           Expression severity)
                    throws ExceptionHugin

Constructs a new AggregateExpression. This represents the distribution of the sum of a random number of independent identically distributed random variables. The distribution of the number of variables is specified by the frequency argument (which must be a numbered node), and the distribution of each random variable in the sum is specified by the severity argument (which must be an interval node).

This expression is only allowed for DiscreteFunctionNodes of interval subtype.

Parameters:

frequency - the distribution of the number of variables in the sum

severity - the distribution of each random variable in the sum

Method Detail

getOperator

public int getOperator()

Returns the operator of this Expression.
