Wishart kernel density estimation for strongly mixing time series on the cone of positive definite matrices
Léo R. Belzile, Christian Genest, Frédéric Ouimet +1
A Wishart kernel density estimator (KDE) is introduced for density estimation in the cone of positive definite matrices. The estimator is boundary-aware and mitigates the boundary…
On noncentral Wishart mixtures of noncentral Wisharts and their use for testing random effects in factorial design models
Christian Genest, Anne MacKay, Frédéric Ouimet
It is shown that a noncentral Wishart mixture of noncentral Wishart distributions with the same degrees of freedom yields a noncentral Wishart distribution, thereby extending the m…
On the Dirichlet-kernel Gasser--Müller estimator and its competitors for fixed design regression on the simplex
Hanen Daayeb, Christian Genest, Salah Khardani +2
A Dirichlet-kernel Gasser-Müller (D-GM) estimator is introduced for fixed design regression on the simplex, extending the univariate analog due to Chen [Statist. Sinica, vol. 10(1)…
