| Abstract: | Under certain mild conditions based on fractional imputation, it is shown that the asymptotic distributions of the empirical likelihood ratio statistics for various differences of two non-parametric populations are scaled X_1~2, which can be used to construct empirical likelihood confidence intervals for the differences. |
