A Bernstein polynomial approach for the estimation of cumulative distribution functions in the presence of missing data
Rihab Gharbi, Wissem Jedidi, Salah Khardani +1
We study nonparametric estimation of univariate cumulative distribution functions (CDFs) pertaining to data missing at random. The proposed estimators smooth the inverse probabilit…
Bernstein-smoothed estimation and bootstrap inference for the lower-tail Spearman's rho curve
Frédéric Ouimet, Guanjie Lyu, Selim Orhun Susam
This paper studies a Bernstein-smoothed plug-in estimator for the lower-tail Spearman's rho curve, a rank-based measure of local concordance defined through a normalized copula int…
Dirichlet kernel density estimation for strongly mixing sequences on the simplex
Hanen Daayeb, Salah Khardani, Frédéric Ouimet
This paper investigates the theoretical properties of Dirichlet kernel density estimators for compositional data supported on simplices, for the first time addressing scenarios inv…
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)…
