  The family of stable distributions received extensive applications in many
fields of studies since it incorporates both the skewness and heavy tails. In
this paper, we introduce a package written in the R language called
alphastable. The alphastable performs a variety of tasks including: 1-
generating random numbers from univariate, truncated, and multivariate stable
distributions. 2- computing the probability density function of univariate and
multivariate elliptically contoured stable distributions, 3- computing the
distribution function of univariate stable distributions, 4- estimating the
parameters of univariate symmetric stable, univariate Cauchy, mixture of
Cauchy, mixture of univariate symmetric stable, multivariate elliptically
contoured stable, and multivariate strictly stable distributions. This package,
as it will be shown, is very useful for modelling data in univariate and
multivariate cases that arise in the fields of finance and economics.
