The double Pareto lognormal distribution is sufficiently flexible to model heavy tails and skewness in insurance claim data, evident in the accompanying graph.

The EM algorithm developed in our paper allows the parameters of the model to be estimated using the formulae below, often more easily than for the more commonly used generalized beta distribution of the second kind.
