%description
Provides utilities for estimation for the multivariate inverse Gaussian
distribution of Minami (2003) <doi:10.1081/STA-120025379>, including
random vector generation and explicit estimators of the location vector
and scale matrix. The package implements kernel density estimators
discussed in Belzile, Desgagnes, Genest and Ouimet (2024)
<doi:10.48550/arXiv.2209.04757> for smoothing multivariate data on
half-spaces.
