Semiparametric copula-based quantile regression for semicontinuous outcomes with application to healthcare data
Guanjie Lyu, Mohamed Belalia, Abdulkadir Hussein
A semiparametric copula-based two-part quantile regression framework is developed for the analysis of semicontinuous outcomes characterized by a point mass at zero and a continuous…
Dirichlet kernel density estimation on the simplex with missing data
Sami Baraket, Hanen Daayeb, Salah Khardani +2
Nonparametric density estimation for compositional data supported on the simplex is examined under a missing at random mechanism. Rather than imputing missing values and estimating…
Testing equality between two-sample dependence structure using Bernstein polynomials
Guanjie Lyu, Mohamed Belalia
Tests of equality of copulas between two samples are introduced and studied using the empirical Bernstein copula process. Three statistics are proposed and their asymptotic propert…
Testing Symmetry for Bivariate Copulas using Bernstein Polynomials
Guanjie Lyu, Mohamed Belalia
In this work, tests of symmetry for bivariate copulas are introduced and studied using empirical Bernstein copula process. Three statistics are proposed and their asymptotic proper…
