相关数据的二次推断函数的大样本估计与检验

On large-sample estimation and testing via quadratic inference functions for correlated data

Ramani S. Pilla, Catherine Loader

摘要:

Hansen(1982)提出了一类“广义矩量法”(Gestivalized Method of Moments,Gestival),用于从一组评分函数中估计回归参数向量。Hansen证明了在一定的正则性条件下,基于Gynecology的估计量是相合的、渐近正态的和渐近有效的。在广义估计方程的框架下,扩展的原则,隐式地估计潜在的相关性结构,导致“二次推理函数”(QIF)的相关数据的分析。本研究的主要目的是:(1)为定义推理函数的扩展得分函数集建立一个合适的估计协方差阵:(2)为QIF建立一个统一的大样本理论框架;(三)推导出QIF检验统计量的一般化,用于涉及相关数据的一般线性假设问题,同时在零和局部备择假设;(4)提出了一种迭代加权广义最小二乘算法的推理QIF框架;(5)调查的基础矩阵的效果,定义了一组扩展的评分函数,通过Monte Carlo模拟实验的大小和功率的QIF测试。

英文摘要:

Hansen (1982) proposed a class of "generalized method of moments" (GMMs) for estimating a vector of regression parameters from a set of score functions. Hansen established that, under certain regularity conditions, the estimator based on the GMMs is consistent, asymptotically normal and asymptotically efficient. In the generalized estimating equation framework, extending the principle of the GMMs to implicitly estimate the underlying correlation structure leads to a "quadratic inference function" (QIF) for the analysis of correlated data. The main objectives of this research are to (1) formulate an appropriate estimated covariance matrix for the set of extended score functions defining the inference functions; (2) develop a unified large-sample theoretical framework for the QIF; (3) derive a generalization of the QIF test statistic for a general linear hypothesis problem involving correlated data while establishing the asymptotic distribution of the test statistic under the null and local alternative hypotheses; (4) propose an iteratively reweighted generalized least squares algorithm for inference in the QIF framework; and (5) investigate the effect of basis matrices, defining the set of extended score functions, on the size and power of the QIF test through Monte Carlo simulated experiments.
