The Pareto distribution is a continuous, long-tailed distribution that is commonly used to model traffic patterns in network modeling, the size of insurance claims, and income levels in economic modeling.
It requires two inputs, a shape parameter (a) and a scale parameter (b), which defines the lower bound and mode of the Pareto distribution. Both of these parameters must be positive numbers.
GoldSim also allows you to truncate the distribution by checking the Truncated box and specifying a Maximum.
