摘要
考虑具有测量误差的线性模型在参数分量具有精确的线性约束条件下的统计推理,提出了偏差校正的拉格朗日乘子检验统计量,得到了受约束的纠偏最小二乘估计量,并在一定的正则性条件下,证明了所得估计量渐近服从正态分布.最后通过数值模拟研究了所提方法的有限样本性质.
In this paper,we consider statistical inference for a linear model with measurement error when exact linear restriction on the parametric component is assumed to hold.We proposed a bias-corrected Lagrange multiplier test statistic,and obtain the constrained bias-corrected least square estimator.Under certain regularity conditions,the asymptotic normality for the estimator are proved.Finally,the numerical simulations are conducted to illustrate the finite sample performance of the proposed methods.
