Which distribution is commonly used for modeling loss amounts?
Understand the Problem
The question is asking which statistical distribution is typically used to model loss amounts. To answer this, we need to evaluate each option in terms of its application in modeling financial or insurance losses.
Answer
Lognormal and Gamma distributions
The Lognormal and Gamma distributions are commonly used for modeling loss amounts.
Answer for screen readers
The Lognormal and Gamma distributions are commonly used for modeling loss amounts.
More Information
The choice of distribution for modeling loss amounts often depends on the characteristics of the loss being modeled, such as the skewness and presence of a long tail in the distribution. Lognormal distributions are suitable for skewed loss data, while Gamma distributions can model small to medium losses.
Tips
A common mistake is choosing a distribution without considering the skewness and distribution tail characteristics of the actual loss data.
