Firstly, we provide some Confidence Distributions to the Behrens-Fisher problem, and then we give the Confidence Distribution method to the Behrens-Fisher problem. Finally, we compare the “combination” and the “single” through the numerical simulation.enBehrens-Fisher ProblemCombining Confidence DistributionInterval Estimation ComponentArticle
