    Joint empirical likelihood confidence regions for a finite number of quantiles under strong mixing samples

    In this paper, we obtain the joint empirical likelihood confidence regions for a finite number of quantiles under strong mixing samples. As an application of this result, the empirical likelihood confidence in...

    Empirical likelihood for quantiles under associated samples

    The construction of confidence intervals for quantiles of a population under a associated sample is studied by using the blockwise technique. It is shown that the blockwise empirical likelihood (EL) ratio stat...

    Empilrical likelihood for non-parametric regression models with missing responses: Multiple design case

    Empirical likelihood (EL) ratio statistic on θ = g(x) is constructed based on the inverse probability weighted imputation approach in a nonparametric regression model Y = g(x)+ɛ (x ∈ [0, 1] p ...

    Modified likelihood ratio test for homogeneity in normal mixtures with two samples

    This paper investigates the modified likelihood ratio test(LRT) for homogeneity in normal mixtures of two samples with mixing proportions unknown. It is proved that the limit distribution of the modified likel...
