男性和女性等位基因频率相等的标准统计检验和哈代-温伯格平衡检验通过其假设紧密联系在一起。等位基因频率相等的检验假设哈代-温伯格平衡,而哈代-温伯格平衡的通常卡方或精确检验假设两性等位基因频率相等。在本文中,我们提出的方法来打破这种相互依赖的假设,提出了一个综合的确切的测试,可以测试这两个假设联合,以及似然比的方法,允许这些现象进行测试,联合和单独的。这些测试是用1000个基因组项目的数据来说明的。
Standard statistical tests for equality of allele frequencies in males and females and tests for Hardy‐Weinberg equilibrium are tightly linked by their assumptions. Tests for equality of allele frequencies assume Hardy‐Weinberg equilibrium, whereas the usual chi‐square or exact test for Hardy‐Weinberg equilibrium assume equality of allele frequencies in the sexes. In this paper, we propose ways to break this interdependence in assumptions of the two tests by proposing an omnibus exact test that can test both hypotheses jointly, as well as a likelihood ratio approach that permits these phenomena to be tested both jointly and separately. The tests are illustrated with data from the 1000 Genomes project.
