Empirical likelihood confidence intervals on the mean differences after inverse probability weighted imputation
Journal Title: Scholars Journal of Physics, Mathematics and Statistics - Year 2017, Vol 4, Issue 3
Abstract
Consider two linear models with missing data, where the covariates are not missing and response variables are missing at random (MAR). The inverse probability weighted imputation is used to impute the missing data of response variables. We construct the empirical log-likelihood ratios on mean differences of two response variables. And the asymptotic distributions for the empirical log-likelihood ratios of mean differences of response variables are standard comparing with the results of previous studies. The empirical likelihood confidence intervals for mean differences of response variables is more accurate because the errors caused right of the coefficient estimates is reduced.

I have already discovered a simple proof of the Riemann Hypothesis. The hypothesis states that the nontrivial zeros of the Riemann zeta function have real part equal to 0.5 . I assume that any such zero is s =a+ bi .I us...
