标题： Comparing Two Approaches in Heteroscedastic Regression Models

摘要： 最近，Sadooghi-alvandi 等人（2016）提出了一种广义检验方法，Xu 和 Li（2018）提出了一种置信方法，以检验具有不等方差的多个回归模型中系数的相等性。在本文中，表明这些方法中的所考虑量是同分布的，因此这些方法是相同的。此外，这一结果也适用于单因素方差分析问题。 显示英文摘要

摘要： Recently, a generalized test approach is proposed by Sadooghi-alvandi et al. (2016) and a fiducial approach is proposed by Xu and Li (2018) to test the equality of coefficients in several regression models with unequal variances. In this paper, it is shown that the considered quantities in these approaches are identically distributed and therefore, these approaches are same. Also, this result satisfies for the one-way ANOVA problem.
