AI 中文摘要
我们引入了用于双向列联表中近似独立性的新等价检验。临界值通过渐近计算得出。通过自助法提高了检验的有限样本性能。开发了边界点估计器以使基于自助法的检验在统计上有效且计算可行。我们通过模拟比较了不同表大小下所提出检验的性能。然后将这些检验应用于实际数据集。这些检验在R中实现且可在线获取。
英文摘要
We introduce new equivalence tests for approximate independence in two-way contingency tables. The critical values are calculated asymptotically. The finite sample performance of the tests is improved by means of the bootstrap. An estimator of boundary points is developed to make the bootstrap based tests statistically efficient and computationally feasible. We compare the performance of the proposed tests for different table sizes by simulation. Then we apply the tests to real data sets. The tests are implemented in R and available online, see [https://github.com/TestingEquivalence/EquivalenceTestIndependenceR].
