Abstract:In this paper, we establish the random-effect model of bivariate meta-analysis based on the difference mean. Under the assumption of the multilevel normal distribution of the difference mean, we obtain the maximum likelihood estimator ˆM L µ of the difference mean by the method of maximum likelihood estimate. We conclude that the maximum likelihood estimator ˆM L μ of the difference mean is unbiased for the difference mean effect μ. In addition, we get the corresponding covariance matrix and the () 1 100% − α … Show more
