Free SOA Exam FAM (Fundamentals of Actuarial Mathematics) Severity, Frequency, and Aggregate Models Practice Questions
Severity, frequency, and aggregate loss models on SOA Exam FAM test parametric distributions (exponential, Pareto, lognormal), compound Poisson models, and the Panjer recursive method for computing aggregate loss probabilities.
Sample Questions
Subadditivity is one of the four axioms of coherent risk measures (monotonicity, positive homogeneity, translation invariance, subadditivity).
, while is the minimum possible value (often 0 for loss distributions). Since generally does not equal the minimum, the statement that TVaR at level equals VaR at level is false.
For compound Poisson (, ), Panjer's recursion simplifies to: For : . Verification by direct calculation: requires either one claim of size 2 or two claims each of size 1. . Common error: Applying the non-simplified formula incorrectly and getting , which is rather than .
