比较回归曲线--一个$L^1$观点

Comparing regression curves -- an $L^1$-point of view

Patrick Bastian, Holger Dette, Lukas Koletzko, Kathrin Möllenhoff

摘要:

在本文中,我们比较两个回归曲线,通过测量它们之间的差异的两条曲线,由它们的$L^1$距离表示的面积。我们为这一测量和统计检验开发了渐近置信区间,以研究两条曲线的相似性/等效性。为了得到具有良好有限样本性质的等价性检验程序,本文提出了一种Bootstrap方法,并严格证明了该方法的一致性。有限样本的性质进行了研究,通过一个小的模拟研究。

英文摘要:

In this paper we compare two regression curves by measuring their difference by the area between the two curves, represented by their $L^1$-distance. We develop asymptotic confidence intervals for this measure and statistical tests to investigate the similarity/equivalence of the two curves. Bootstrap methodology specifically designed for equivalence testing is developed to obtain procedures with good finite sample properties and its consistency is rigorously proved. The finite sample properties are investigated by means of a small simulation study.
