When modeling operational risk using separate distributions for loss frequency and loss severity, which of the following is true?

Show Suggested Answer Hide Answer
Suggested Answer: A

When modeling operational loss frequency distribution (which, for example, may be based upon a Poisson distribution) and a loss severity distribution (for example, based upon a lognormal distribution), it is assumed that the frequency of losses and the severity of the losses are completely independent and do not impact each other. Therefore Choice 'a' is correct, and the others are not valid assumptions underlying the operational loss modeling.

Once each of these distributions has been built, a random number is drawn from each to determine a loss scenario. The process is repeated many times as part of a Monte Carlo simulation to get a the loss distribution.

C is interesting, but I think it’s more about context than units.

Wait, are we sure about A? Seems too simplistic.

I think B is more accurate, they can be correlated in some cases.

Totally agree with A! They’re separate for a reason.

Conditional probabilities sound familiar, but I can't remember if that's the right approach for modeling these two aspects together.

I feel like loss severity and frequency should be in the same units, but I might be mixing it up with another topic we covered.

I remember a practice question where they discussed bivariate models, but I can't recall if they mentioned correlation specifically.

I think loss severity and frequency are often treated as independent, but I'm not entirely sure if that's always the case.
