通过φ-偏差的拟合优度检验

Goodness-of-fit tests via phi-divergences

Leah Jager, Jon A. Wellner

摘要:

介绍并研究了基于$ϕ$ -发散性的统一的拟合优度检验族。新的检验统计量族$S_n(s)$包括Anderson-Darling统计量的上确界形式和Berk和Jones [Z.华什弗鲁Gebiete 47(1979)47- 59]作为特例(分别为$s=2$和$s=1$)。我们还介绍了新统计的积分版本。我们证明了Berk和Jones [Z.华什弗鲁Gebiete 47(1979)47- 59]和Wellner和Koltchinskii [高维概率III(2003)321- 332. Birkhäuser,Basel]的Berk-Jones统计量适用于整个统计量族$S_n(s)$和$s\in[-1,2]$。在幂行为方面,我们研究了固定方案下的检验统计量,并推广了Berk和Jones关于其统计量的“Poisson边界”现象。我们还推广了Donoho和Jin [Ann. Statistist. 32(2004)962--994],表明我们对$s\in[-1,2]$的所有新测试对于正常移位混合物替代物具有与Tukey的"更高临界“统计量和Berk-Jones统计量相同的"最优检测边界”。

英文摘要:

A unified family of goodness-of-fit tests based on $ϕ$-divergences is introduced and studied. The new family of test statistics $S_n(s)$ includes both the supremum version of the Anderson--Darling statistic and the test statistic of Berk and Jones [Z. Wahrsch. Verw. Gebiete 47 (1979) 47--59] as special cases ($s=2$ and $s=1$, resp.). We also introduce integral versions of the new statistics. We show that the asymptotic null distribution theory of Berk and Jones [Z. Wahrsch. Verw. Gebiete 47 (1979) 47--59] and Wellner and Koltchinskii [High Dimensional Probability III (2003) 321--332. Birkhäuser, Basel] for the Berk--Jones statistic applies to the whole family of statistics $S_n(s)$ with $s\in[-1,2]$. On the side of power behavior, we study the test statistics under fixed alternatives and give extensions of the ``Poisson boundary'' phenomena noted by Berk and Jones for their statistic. We also extend the results of Donoho and Jin [Ann. Statist. 32 (2004) 962--994] by showing that all our new tests for $s\in[-1,2]$ have the same ``optimal detection boundary'' for normal shift mixture alternatives as Tukey's ``higher-criticism'' statistic and the Berk--Jones statistic.
