Explanation:
A is correct - In the standardized approach for operational risk calculation, banks divide their activities into different business lines and calculate a beta factor for each line.
B is correct - Economic capital indeed covers the difference between worst-case loss (Value at Risk) and expected loss.
C is correct - Loss severity is typically modeled with a lognormal distribution, while loss frequency is modeled using a Poisson distribution in operational risk modeling.
D is not mentioned in the provided text - The text cuts off before completing this statement, so we cannot verify its accuracy from the given information.

In the standardized approach to calculating operational risk, which of the following statements is correct?
A
A bank's activities are divided up into several different business lines, and a beta factor is calculated for each line of business.
B
Economic capital covers the difference between the worst-case loss and the expected loss.
C
Loss severity tends to be modeled with a lognormal distribution, but loss frequency is typically modeled using a Poisson distribution.
D
Operational loss data available from data vendors tends to be biased towards large losses.
