%description
Random sampling from distributions with user-specified population
covariance matrix. Marginal information may be fully specified, for which
the package implements the VITA (VIne-To-Anything) algorithm Grønneberg
and Foldnes (2017) <doi:10.1007/s11336-017-9569-6>.  See also Grønneberg,
Foldnes and Marcoulides (2022) <doi:10.18637/jss.v102.i03>. Alternatively,
marginal skewness and kurtosis may be specified, for which the package
implements the IG (independent generator) and PLSIM (piecewise linear)
algorithms, see Foldnes and Olsson (2016)
<doi:10.1080/00273171.2015.1133274> and Foldnes and Grønneberg (2021)
<doi:10.1080/10705511.2021.1949323>, respectively.
