drivers is 100 (shown in Figure3.25). The values are close here, so the FFT
approximation can be used.

3.7 Using Objects without Simulation
Objects, as we have seen, are very useful when constructing models and
when implementing Aggregate distributions. In fact, the use of Objects can
sometimes even enable us to bypass the need to Monte Carlo simulate at all!
We will look at how this can be done using VoseAggregateFFT, but this also
applies to any Distribution Object in ModelRisk. For some models, ModelRisk
can use the frequency and severity Distribution Objects to calculate dif
