多相随机非线性模型中的M-估计

The M-estimator in a multi-phase random nonlinear model

Gabriela Ciuperca

摘要:

本文研究了在未知时刻具有多个变点的非线性回归模型的M-估计。多阶段随机设计回归模型在每个变点处不连续,具有任意误差$ε$。在已知跳数的情况下,研究了突变点位置和回归参数的M-估计。这些估计是相容的,回归参数估计的分布是高斯分布。每个变点的估计量以速率$n^{-1}$收敛到独立复合Poisson过程的最小极小值。这些结果对一大类误差分布都是有效的。

英文摘要:

This paper considers M-estimation of a nonlinear regression model with multiple change-points occuring at unknown times. The multi-phase random design regression model, discontinuous in each change-point, have an arbitrary error $ε$. In the case when the number of jumps is known, the M-estimator of locations of breaks and of regression parameters are studied. These estimators are consistent and the distribution of the regression parameter estimators is Gaussian. The estimator of each change-point converges, with the rate $n^{-1}$, to the smallest minimizer of the independent compound Poisson processes. The results are valid for a large class of error distributions.
