摘要
针对含测量误差高维数据半参数变系数部分线性模型的经验似然校正问题,通过对对数经验似然比统计量统计性质的分析与计算,提出一种新的估计对数经验似然比统计量的期望和方差的方法,得到校正的对数经验似然比统计量的渐近分布,说明其渐近统计性质优于传统方法.并利用数值模拟证明了所提方法的优良性质.
Aiming at the problem of the empirical likelihood calibration for high-dimensional semiparametric varying-coefficient partially linear errors-in-variables model,through analysis of the statistical properties of the empirical log-likelihood ratio and calculation,a new method to estimate the expectation and variance of the empirical log-likelihood ratio is given.The asymptotic distribution of the corrected empirical log-likelihood ratio is obtained,whose statistical properties are better than those of the traditional method.Simulation indicates that the proposed method performs well.
