%description
Estimation of a lognormal - Generalized Pareto mixture via the
Expectation-Maximization algorithm. Computation of bootstrap standard
errors is supported and performed via parallel computing. Functions for
random number simulation and density evaluation are also available. For
more details see Bee and Santi (2025) <doi:10.48550/arXiv.2505.22507>.
