精确线性约束条件下众数回归模型的参数估计
摘要:
研究了众数线性回归模型中回归系数具有精确线性约束条件下的估计问题,提出了拉格朗日乘子的众数估计量,证明了所得估计量的相合性及渐近正态性,并给出了一个求解最大化目标函数的迭代算法,最后通过数值模拟研究了所提方法的良好有限样本性质.
This article considers the estimation problem of regression coefficients in modal linear regression models with exact linear constraints, A mode estimator with Lagrange multipliers is proposed, and the consistency and asymptotic normality of the obtained estimator are established, Furthermore, an iterative algorithm is proposed to solve the maximization objective funetion, Simulation studies are carried out to illustrate the finite sample performance of the proposed method.
