gauss_kdens_arma

Given a data matrix over a half-space defined by <code>beta</code>,
compute the log density of the asymmetric truncated Gaussian kernel density estimator,
taking in turn an observation as location vector.

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.
