泛函线性模型中误差分布变化的检验

Testing for changes in the error distribution in functional linear models

Natalie Neumeyer, Leonie Selk

AI总结:

针对泛函线性模型,提出基于序贯残差经验分布函数的误差分布变点检验,该检验渐近分布自由且对单变点备择一致,并证明变点估计量的一致性。

摘要:

我们考虑具有标量响应和来自可分希尔伯特空间协变量的线性模型。目的是基于序贯残差经验分布函数检测误差分布中的变点。与具有标量或向量值协变量的回归模型相比,在具有无限维协变量的模型中,这些估计函数的展开更具挑战性,因为参数估计量的收敛速度较慢。然而,所提出的变点检验是渐近分布自由的,并且对单变点备择假设是一致的。在后一种情况下,我们还证明了变点估计量的一致性。

英文摘要:

We consider linear models with scalar responses and covariates from a separable Hilbert space. The aim is to detect change points in the error distribution, based on sequential residual empirical distribution functions. Expansions for those estimated functions are more challenging in models with infinite-dimensional covariates than in regression models with scalar or vector-valued covariates due to a slower rate of convergence of the parameter estimators. Yet the suggested change point test is asymptotically distribution-free and consistent for one-change point alternatives. In the latter case we also show consistency of a change point estimator.
