Detailed Description
Expression class representing the aggregate() operator.
Constructor & Destructor Documentation
| HAPI::AggregateExpression::AggregateExpression | ( | Expression * | frequency, |
| Expression * | severity | ||
| ) | [inline] |
Construct 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 a DiscreteFunctionNode 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
