Abstract:

In this paper, we consider the interval estimation and hypothesis testing problems for the common location parameter of several skew-normal populations when the scale parameters and skewness parameters are unknown. Firstly, we estimate the unknown parameters using the methods of moment estimation and maximum likelihood estimation. Secondly, the Bootstrap confidence intervals and Bootstrap test statistics are constructed, which generalize the results given by Xu [1] under several normal populations. Thirdly, the Monte Carlo simulation results indicate that the Bootstrap confidence intervals based on the methods of moment estimation and maximum penalized likelihood estimation perform better than other four confidence intervals. Finally, the above approaches are applied to the real data examples of regional gross domestic product of China and bioavailability in order to verify the reasonableness and effectiveness of the proposed approaches.

Key words: Skew-normal population, Common location parameter, Moment estimation, Maximum likelihood estimation, Bootstrap confidence interval
