%description
Provides various functions for parameter estimation of one-dimensional
stable distributions and their mixtures. It implements a diverse set of
estimation methods, including quantile-based approaches, regression
methods based on the empirical characteristic function (empirical, kernel,
and recursive), and maximum likelihood estimation. For mixture models, it
provides stochastic expectation–maximization (SEM) algorithms and Bayesian
estimation methods using sampling and importance sampling to overcome the
long burn-in period of Markov Chain Monte Carlo (MCMC) strategies. The
package also includes tools and statistical tests for analyzing whether a
dataset follows a stable distribution. Some of the implemented methods are
described in Hajjaji, O., Manou-Abi, S. M., and Slaoui, Y. (2024)
<doi:10.1080/02664763.2024.2434627>.
