Lomax distribution
The shifted Pareto distribution is considered in the mathematical statistics probability distribution, which is particularly suitable for modeling of large losses, especially in industrial and reinsurance. Mathematically, these are a Pareto distribution whose distribution curve is shifted by a fixed parameter value, hence the name of this distribution is derived.
Definition
A continuous random variable satisfies the shifted Pareto distribution with parameters, and when the probability density
Possesses.
Properties
Expected value
The expected value is given by:
Variance
The variance can be specified as
Standard deviation
From the expected value and variance, the standard deviation is
Coefficient of variation
From expectation and variance one obtains the coefficient of variation
Skew
Results for the skewness
Characteristic function
The characteristic function for the shifted Pareto distribution can not be specified in closed form.
Moment generating function
The moment generating function for the shifted Pareto distribution can not be specified in closed form.
