In this paper, we discuss the construction of the confidence intervals for the regression vector [beta] in a linear model under negatively associated errors. It is shown that the blockwise empirical likelihood (EL) ratio statistic for [beta] is asymptotically [chi]2-type distributed. The result...

In this paper we consider the problem of testing the hypothesis about the sub-mean vector. For this propose, the asymptotic expansion of the null distribution of Rao's U-statistic under a general condition is obtained up to order of n-1. The same problem in the k-sample case is also...
