报告摘要：In this paper, we proposed a test procedure based on random integration and 
-approximate method to deal with the problem of heteroskedastic general linear hypothesis testing (GLHT) in high-dimensional settings. The asymptotic distributions of the proposed test statistic was obtained under the null and the alternative hypotheses, respectively. The results showed that it was more reasonable to approximate the distributions of the new test using the distribution of the chi-square type mixture. Numerical simulations and real data analysis further showed that our proposed test was more powerful than competing tests.
